The present invention relates to a system, job management server and control method thereof, job processing apparatus and control method thereof, and non-transitory computer-readable medium.
In recent years, a peripheral apparatus control system, which connects peripheral apparatuses to an information processing apparatus by utilizing various interfaces such as USB, Ethernet®, and a wireless LAN, is effectively used in various sites such as home and an office. As examples of peripheral apparatuses, a printer, copying machine, facsimile, scanner, digital camera, MFP (Multi-Function Peripheral) thereof, and the like are known.
To a printer and MFP of these peripheral apparatuses, for example, Google Inc. provides a cloud printing service called Google Cloud Print® (to be abbreviated as “GCP” hereinafter) utilizing the Internet. Using the cloud printing service, the user can launch (utilise) a document creation application (Web application) or the like using a Web browser installed in a personal computer (to be abbreviated as “PC” hereinafter) or mobile terminal, and can print a document using the printer or HFP.
Some advanced MFPs incorporate a Web browser. During an operation of a Web browser of an MFP by a certain user, that MFP can simultaneously execute print processing of a print job which is issued by another user from a PC or mobile terminal to the MFP while executing parallel processing in the background-Likewise, during an operation of a Web browser of an MFP by a certain user, when another user scans an original using that MFP from a PC, mobile terminal, or the like, the MFP can simultaneously scan the original while executing processing related to the Web browser. The user can launch (utilize) a document creation Web application using the Web browser incorporated in such MFP without using the PC or mobile terminal and can print a document using the MFP via the Internet. Also, the user can scan an original using the MFP while operating the Web browser incorporated in that MFP, and can upload an obtained scan image onto an image storage Web service or the like via the Internet.
In case of the scan, as another technique especially related to exclusive control of a job, Japanese Patent Laid-Open No. 2009-267701 is known. Japanese Patent Laid-Open No. 2009-267701 starts exclusive control which is executed not to accept any scan-related requests from terminal apparatuses other than that of a distribution destination before a scan-related request is accepted, and ends the exclusive control after scanned scan data is distributed to the terminal apparatus of the distribution destination.
A case will be examined below wherein the control system utilizing the aforementioned advanced MFP is broken down to that utilizing a low-end (that is, low-function) MFP. For example, some low-end MFPs incorporate a Web browser. Such low-end MFP includes a low-speed CPU, small-capacity memory (RAM), and the like, and often does not include a sufficient storage area. For this reason, due to insufficient hardware resource, during an operation of a Web browser of the MFP by a certain user, the MFP cannot simultaneously execute print processing of a print job which is issued by another user from a PC, mobile terminal, or the like. Also, during an operation of the Web browser of the MFP by a certain user, even when another user wants to scan an original using the MFP from a PC, mobile terminal, or the like, the MFP cannot scan that original.
A case will be examined below wherein print processing is executed using a low-end MFP, which cannot simultaneously execute print processing while executing parallel processing in the background. When a certain user launches a Web browser of the low-end MFP, and operates a document creation application or the like, that user occupies that MFP. The operability of the user when the user operates the document creation application or the like, and wants to execute print processing using the MFP will be examined. In this case, it is desired that immediately after the user makes a print start operation, a print job issued by the print start operation is immediately executed by that MFP without being interrupted by an external print job issued from another PC or the like.
A case will be examined below wherein, for example, when a certain user (user A) launches a Web browser of the MFP and operates a document creation application, another user (user B) launches a Web browser of a PC and operates a document creation application to execute print processing of documents of 100 pages. In this case, the document creation application issues a print job of the user B to the MFP. However, since the user A is using the Web browser at this MFP, print processing of the print job of the user B is not executed at this time. After that, when the user A operates the document creation application to execute print processing of documents of 3 pages, the document creation application issues a print job of the user A to the MFP. Then, after the user A closes the Web browser, the MFP starts print processing for the issued print job. However, when the MFP processes the print job of the user B issued earlier and executes print processing, the user has to wait until the print processing for 100 pages of the user B is complete. Then, before the print processing for 100 pages of the user B is complete, the user A cannot obtain printed products of his or her documents of 3 pages. In this manner, when the print job of the user A who operates the Web browser of the low-end MFP is interrupted by the print job issued by the user B by operating the Web browser, the operability drops considerably. The same applies to a scan job.
Furthermore, a case will be examined below wherein as for a job issued from each Web application by operating a Web browser of an MFP by a user, a server transmits that job notification to an MFP as a processing target. In this case, when excessive job notifications are transmitted, wasteful data communications are generated to increase the load on the server, a data volume on a communication channel increases, and higher communication cost is required according to the data traffic on the Internet. As a result, system building cost and service maintenance cost are increased.
The present invention has been made in consideration of the aforementioned problems, and, for example, in a low-end MFP prevents an interruption of a job issued from a PC or the like, and preferentially executes a job issued from an application when a user operates a Web browser of an MFP.

In the PCs 2 and 5, a Windows® Server OS available from Microsoft Corporation is installed. In the PC 7, an OS equivalent to Linux® is installed. The PCs 1, 2, 5, and 7 are respectively connected to networks 4, 8, 10, and 6 configured by interfaces I/Fs) such as Ethernet®, and are also connected to the internet 12. Note that the network interface may be either a wired or wireless interface.
Each of MFPs (multi-Function Peripherals) 3 and 103 includes a color inkjet printer, color facsimile, color scanner, external storage for a flash memory, and the like, and is an example of a peripheral apparatus. The following description will be given under the assumption that each of the MFPs 3 and 103 is that having a model name “Kmmn” available from Company ABC. Note that as peripheral apparatuses, a printer, copying machine, facsimile, scanner, digital camera, apparatus which includes these multi-functions, and the like may be used. Each of the MFPs 3 and 103 includes hardware shown in
A router 13 is, for example, a broadband router including a Wi-Fi® wireless LAN (Wi-Fi BB Router), and is connected to the Internet 12. A mobile terminal 14 corresponds to a mobile phone, mobile information terminal, or the like. The mobile terminal 14 includes hardware shown in
The PCs 1, 2, 5, and 7, the mobile terminal 14, and the MFPs 3 and 103 can make bidirectional communications via the Internet 12. A Web browser 25 is installed in the PC 1, and a Web browser S is installed in the mobile terminal 14. Web browsers 27 and 28 are respectively installed in the MFPs 3 and 103. The Web browsers 27 and 28 are of the same type, but the Web browsers 9, 25, and 27 are respectively of different types. HTTP user agents passed to a document creation APP 145 and cloud scan APP 148 in User-Agent headers of HTTP requests by the Web browsers 9, 25, and 27 are respectively different, and for example, they are defined as follows.
User agent of the Web browser 9 of the mobile terminal 14: User-Agent: XXXX/5.0 (AAAA)
User agent of the Web browser 25 of the PC 1: User-Agent: XXXX/6.0 (CCCC)
User agent of the Web browser 27 of the MFP 3: User-Agent: YYYY/4.0 (DDDD)
“AAAA”, “CCCC”, and “DDDD” represent pieces of information required to identify respective terminals. Each of a document creation APP 145 and cloud scan APP 148 can discriminate whether a terminal of interest is any of the mobile terminal 14, PC 1, and MFP 3 using these pieces of information, and can switch a window to be displayed by that application and internal processing.
An application 145 is a document creation application using a Web service, and will be referred to as a document creation APP 145 hereinafter. An application 146 provides a cloud print service using a Web service, and will be referred to as a cloud print APP 146 hereinafter. An application 147 is that required to read an image and document using a Web service, and will be referred to as a reading APP 147 hereinafter. An application 148 provides a cloud scan service using a Web service, and will be referred to as a cloud scan APP 148 hereinafter.
The cloud print APP 146 has a function equivalent to, for example, the GCP provided by Google Inc. By utilizing this cloud print service, the document creation APP 145 is executed from the Web browser 25 of the PC 1 or the Web browser 9 of the mobile terminal 14, an arbitrary document (document file) is opened, and can be printed using the MFP 3 or 103. Kith these applications, the PC 7 functions as a Web application server.
When the MFP includes a rendering function of a PDF file, it can print the print job stored in the print queue. However, a low-end MFP (lower function) does not normally include a rendering function of a PDF file. Therefore, when the print job stored in the print queue is to be printed by such MFP, processing for converting the print image of the PDF file into an image format (for example, a JPEG format) of a type which can be rendered by the low-end MFP as pre-processing becomes necessary.
The cloud scan APP 148 provides a cloud scan service which can upload image data of photos and documents read by the MFPs 3 and 103 onto a data sharing site. As an example of the data sharing site, “Picasa Web Albums” provided by Google Inc. is known. By utilizing such cloud scan service, the MFP reads a photo or the like via the reading APP 147 executed from the Web browser of the PC 1 or mobile terminal 14 to generate image data, and can upload that image data to a Web service such as the data sharing site. An embodiment of the cloud scan will be described later in the third embodiment.
An application 143 provides a proxy service which controls the MFP to support the cloud print service provided by the cloud print APP 146 and the cloud scan service provided by the cloud scan APP 148. The application 143 will be referred to as a proxy APP 143 hereinafter. The proxy APP 143 installed in the PC 2 simultaneously manages, for example, 5000 MFPs. Then, the proxy APP 143 controls these MFPs to support the cloud print service provided by the cloud print APP 146 and the cloud scan service provided by the cloud scan APP 148. The proxy APP 143 includes print queues and scan queues shown in
The cloud print APP 146 or cloud scan APP 148 issues and assigns a device ID (identifier), which is expressed by a value unique to each MFP, upon registration of the MFP, and notifies the MFP as a registration target of the device ID. Note that processing related to registration of the MFP uses the conventional method, and a detailed description thereof will not be given.
An application 144 provides an image conversion service for converting a PDF file into a JPEG file, and will be referred to as an image conversion APP 144 hereinafter.

[Processing Sequence]
In
(Processing when MFP Issues Print Instruction)
In step S3604, the MFP 3 receives print job information or reading job information like the following examples, and executes print processing (step S3621) or reading processing (step S3920).
[Example of Print Job Information]
After completion of the print processing or reading processing, the MFP 3 notifies the proxy APP 143 of that information (step S3604). In step S3605, the proxy APP 143 executes job deletion processing shown in
Note that a job request to the MFP 3 is also issued from a device other than the Web browser 27 of the MFP 3, and a job is registered in the queue of the proxy APP 143. For example, when the user issues a print job from the mobile terminal 14 to the MFP 3 in a power-OFF state of the MFP 3, that job is accumulated in the queue, and the MFP 3 normally executes that print job when it is turned on. At this time, the MFP 3 may fail to execute that print job due to an arbitrary internal error or the like, and the job may remain accumulated in the queue in some cases. Alternatively, when the user issues a print job by operating the Web browser 27 of the MFP 3 in a power-ON state of the MFP 3, that job may remain accumulated in the queue due to arbitrary error termination of the Web browser 27 in some cases.
In such situation, when the MFP 3 issues the job obtaining request to the proxy APP 143 in step S3602, whether or not a job to the MFP 3 remains is confirmed. Then, when a job remains in the queue, the MFP 3 normally preferentially executes a job which is issued earlier (the MFP 3 re-executes that job when it has failed to execute that job). That is, even when a Web application is used via the Web browser 27 of the MFP 3, jobs are executed in an order they are issued.
The present invention has as its object to execute a job issued when the user operates the Web browser 27 of the MFP 3 by attaching top priority to that job. For this reason, for example, when the MFP 3 issues a job obtaining request to the proxy APP 143 in step S3602, it designates an option to obtain only a job in a top priority job queue in the job queue shown in
In step S3607, the MFP 3 transitions to a mode for excluding an externally input job, and permitting only acceptance of a job notification, and the process advances to step S3608.
When the user presses the print menu 401 shown in
Upon acceptance of the print request from the MFP 3, the document creation APP 145 issues a print job to the cloud print APP 146 (step S3613). At this time, the print request includes information indicating that a host which issued the print request of the print job is the MFP (host=mfp), and information indicating that this print request does not require any job notification to the MFP 3 (notification=no) according to the print request received from the MFP 3. The cloud print APP 146 inputs the print job to the print queue of the proxy APP 143 (step S3614).
At this time, the cloud print APP 146 further adds issued year/month/day/time information of the print job to the print job. The proxy APP 143 executes job registration processing shown in
The cloud print APP 146 returns the job ID (print job ID) returned from the proxy APP 143 to the document creation APP 145. Furthermore, in response to acceptance of the job ID from the cloud print APP 146, the document creation APP 145 notifies the MFP 3 of information indicating that the print job is issued. At this time, the document creation APP 145 notifies the MFP 3 of the job ID (print job ID) returned from the cloud print APP 146 together. This notification can be attained by utilizing, for example, the JavaScript® embedded in Web page information. At the issuance timing of the print job, the Web browser 27 executes a Print function, which is exported by the MFP 3 to the Web browser 27, via the JavaScript®.
When the Print function is called, the MFP 3 receives information representing that the print job is registered in the print queue. At this time, the job ID (print job ID) included in the received information is passed to the MFP 3 as an argument of the Print function, and the MFP 3 also obtains the job ID (print job ID) generated by the proxy APP 143 (step S3617). In this manner, since the MFP 3 includes the Print function, and the Web browser 27 utilizes the Print function via the JavaScript®, an unnecessary job notification can be omitted. As a result, reductions of the load on the server, the data traffic of the communication channel, and the data communication cost can be attained.
In step S3617, upon reception of information indicating that the print job has already been issued, the MFP 3 displays a message indicating that execution of print-related processing is in progress like “in print preparation” or “print in progress” on the display unit 21. Then, the MFP 3 notifies the user of transition to the print mode (print processing in progress). At this time, the MFP 3 displays this message without using the Web browser 27 so as to reduce the load. The MFP 3 waits for an elapse of an assumed time period (for example, about 3 sec) required for the image conversion APP 144 to complete image conversion (step S4306 in
[Example of Print Job Information]
When the proxy APP 143 does not return any print job information to the MFP 3 for the reason of incompletion of image conversion or the like in step S3620, the MFP 3 repeats the processes of steps S3618 and S3619 until print job information can be obtained or an error is determined after a prescribed retry count (for example, 100) is exceeded. The MFP 3 obtains a storage destination of a print setting file indicating print settings and that of a print image file from the print job information. A combination of the print setting file and print image file will be referred to as “print data” hereinafter. Also, the print setting file will also be referred to as a (print) job ticket. The print setting file is stored at a path (URI) designated by “ticketUri”, and the print image file is stored at a path (URI) designated by “dataUri”. The print setting file is stored in the HDD 202 in the PC 7, and the print image file is stored in the HDD 202 in the PC 5.
The MFP 3 obtains print data by accessing the paths designated by “ticketUri” and “dataUri” in the print job information. The MFP 3 executes print processing according to the contents of the print setting file and print image file, and then notifies the proxy APP 143 of completion of the print processing (step S3621). In step S3622, the proxy APP 143 executes job deletion processing (
After completion of the print processing, the Web browser 27 of the MFP 3 requests the document creation APP 145 to transmit a home window (step S3624). The document creation APP 145 transmits information of the home window to the MFP 3 (step S3625). Then, the MFP 3 displays the home window on the Web browser 27 (step S3624). The MFP 3 waits for a user input operation (step S3626).
(Processing when Mobile Terminal Issues Print Instruction)
When the user presses the print menu 401 shown in
When the user presses the print button 534 while selecting the device choice 536 (MFP 3), the Web browser 9 issues a print request to the document creation APP 145 (step S3706). At this time, the print request includes information indicating that a host (request source) which issued this print request is the mobile terminal 14 (host=phone), and information indicating that this print request requires a job notification to the MFP 3 (notification=yes). Note that the print request may also include other kinds of information such as information indicating a print target document.
Upon acceptance of the print request from the mobile terminal 14, the document creation APP 145 issues a print job to the cloud print APP 146 (step S3707). At this time, the print job includes information indicating that a host which issued the print request of the print job is the mobile terminal (host=phone), and information indicating that the print request requires a job notification to the MFP 3 (notification=yes) according to the print request received from the mobile terminal 14. The cloud print APP 146 inputs the print job to the print queue of the proxy APP 143 (step S3708). At this time, the cloud print APP 146 further adds issued year/month/day/time information of the print job to the print job.
The proxy APP 143 executes job registration processing (
When the proxy APP 143 transmits a job notification to the MFP 3 (step S4309 in

The MFP 3 obtains a storage destination of a print setting file which represents print settings and that of a print image file (“ticketUri” and “dataUri”) from the print job information. The MFP 3 obtains print data by accessing paths (URIs) designated by “ticketUri” and “dataUri”. The MFP 3 executes print processing according to the contents of the print setting file and print image file, and then notifies the proxy APP 143 of completion of the print processing (step S3717). In step S3719, the proxy APP 143 executes job deletion processing (
(Job Registration Processing)
The proxy APP 143 confirms a type of a host as a job request source. If the proxy APP 143 determines that the host is the MFP (host=mfp) (YES in step S4102), the process advances to step S4103; if it determines that the host is other than the MFP (mobile terminal or PC) (NO in step S4102), the process advances to step S4104. In step S4103, the proxy APP 143 registers the job in the top priority job queue in the job queue shown in
In step S4104, the proxy APP 143 confirms a job type. If the proxy APP 143 determines that the job is a print job (YES in step S4104), the process advances to step S4105; if it determines that the job is other than a print job (reading job) (NO in step S4104), the process advances to step S4106. In step S4105, the proxy APP 143 registers the job at the bottom position of a general print queue in the job queue shown in
(Job Notification Processing)
When the proxy APP 143 specifies the target device (MFP 3 in this case) and requests job notification processing, the processing shown in
In step S4305, the proxy APP 143 requests the image conversion APP 144 to execute image conversion processing related to the print job. The image conversion APP 144 converts a print target image into a file format (JPEG file in this case) printable by the MFP 3 according to the image conversion request from the proxy APP 143 (step S4306). The print target image corresponds to a print target content or a PDF file generated for print processing, which is temporarily stored in the HDD 202 by the document creation APP 145. After completion of the image conversion processing by the image conversion APP 144, the proxy APP 143 refers to detailed information of the print job shown in
In step S4307, the proxy APP 143 refers to the job queue shown in
(Job Information Return Processing)
In
In step S4412, the proxy APP 143 obtains job information registered at the head position in the top priority job queue, and the process advances to step S4413. In step S4405, the proxy APP 143 confirms the presence/absence of a job in a general scan queue. If the proxy APP 143 determines that a job is present in the general scan queue (YES in step S4406), the process advances to step S4407; otherwise (NO in step S4406), the process jumps to step S4408. In step S4407, the proxy APP 143 obtains job information registered at the head position in the general scan queue, and the process advances to step S4413. In step S4408, the proxy APP 143 confirms the presence/absence of a job in a general print queue. If the proxy APP 143 determines that a job is present in the general print queue (YES in step S4409), the process advances to step S4410; otherwise (NO in step S4409), the process advances to step S4411.
In step S4410, the proxy APP 143 obtains job information registered at the head position in the general print queue, and the process advances to step S4413. In step S4411, since there is no job in the job queue of the target device, the proxy APP 143 returns a message indicating the absence of job information to the device as the request source. Then, the process returns to the processing sequence as a call source of this processing (step S4414). In step S4413, the proxy APP 143 returns the job information obtained in step S4412, S4407, or S4410 to that device. Then, the process returns to the processing sequence as a call source of this processing (step S4414).
(Job Notification Reception Processing)
Upon reception of a job notification issued from the proxy APP 143, the MFP 3 starts the job notification reception processing (step S4601) in
In step S4604, the MFP 3 increments the job notification presence information by “1”, and saves it in the RAM 17. Then, the MFP 3 ends this processing sequence (step S4608). In step S4605, the MFP 3 issues a job obtaining request to the proxy APP 143. At this time, the proxy APP 143 executes the job information return processing (

In all the cases except for (6), when the job notification presence information is larger than “0”, the MFP 3 repetitively executes the job confirmation processing (
[Configuration Example of Job Queue]
The job queue in
In this case, a job issued from the application when the user operates the Web browser (Web browser 21) of the device (MFP 3) to input a print or reading processing instruction is determined as a top priority job to give the top priority to the operability of the user who operates the MFP 3. Next, in order to prevent an operation for setting an original on the MFP and executing reading processing by operating a start button on an operation panel (operation unit 20) of the MFP by the user from being interrupted by another job, the second priority is given to the general scan queue. Thus, a reading job issued from the application when the user operates the mobile terminal 14 or the like can be preferentially processed, thus improving the user's operability.
Then, the third priority (lowest priority) is given to the general print queue of these queues. Normally, print processing of a print job issued from the application when the user operates the mobile terminal 14 or the like is automatically executed by the MFP 3 without requiring any user operation. For example, a job registered in the top priority job queue or general scan queue requires a user's MFP operation. By contrast, a job registered in the general print queue normally does not require any user's MFP operation (except for an out-of-paper or out-of-ink state). For this reason, even when the third priority is given to the general print queue, the user's operability is rarely impaired. Note that the aforementioned priority order is an example, and the priorities of the general scan queue and general print queue may be set to be reversed in correspondence with the intended use of the user.
(Table Configuration of Job Information)
(Display Window Example Related to Reading Processing)
Device choices 735, 736, and 737 are those of selectable devices. The device choices 735, 736, and 737 respectively represent those corresponding to an MFP with a model name AkbNmb available from Company GHI, an MFP with a model name Kmmn available from Company ABC (corresponding to the MFP 3 of this embodiment), and an MFP with a model name Xyz available from Company DEF.
Using an original type selection part 730, a type of an original to be read by the MFP 3 is selected from the following options according to a user operation.
An upload destination display part 733 displays an upload destination of an image read by the MFP 3. An upload destination setting button 739 accepts a display instruction of the upload destination selection window 750 shown in
Using a folder designation part 752, the user can designate a folder of an upload destination of an image read by the MFP 3 or 103 from tree-displayed folders.
(Deletion Processing)
In
The proxy APP 143 issues a deletion request of a job ticket to the document creation APP 145 (step S5106). The document creation APP 145 deletes the job ticket (print setting file) according to the job ticket deletion request (step S5107). Then, the proxy APP 143 deletes job information, and deletes that job from the job queue (
In
The cloud scan APP 148 issues a deletion request of job information to the proxy APP 143 (step S5156). The proxy APP 143 deletes the job information according to the job information deletion request, and deletes that job from the job queue (
(Exclusive Control Cancel Processing)
In
Note that the MFP 3 may execute the exclusive control cancel processing due to a time-out. For example, the document creation APP 145 monitors HTTP request intervals from the Web browser 27 of the MFP 3. Then, when an HTTP request from the Web browser 27 is not received for a certain time period (for example, 5 min), the document creation APP 145 notifies the MFP 3 of a time-out via the JavaScript® embedded in Web page information. More specifically, the Web browser 27 executes a Timeout function, which is exported by the MFP 3 to the Web browser 27, via the JavaScript®. When the Timeout function is called, the MFP 3 executes the exclusive control cancel processing shown in
With the aforementioned processing, in the control system including the lower-function MFP, the user's operability can be improved, and reductions of the load on the server, the data traffic of the communication channel, and the data communication cost can be attained.
The second embodiment according to the present invention will foe described below.
[Processing Sequence]
In step S3813 in
In step S3817, upon reception of information indicating that the print job has already been issued from the document creation APP 145, the MFP 3 displays a message indicating that execution of print-related processing is in progress like “in print preparation” or “print in progress” on a display unit 21. Then, the MFP 3 notifies the user of transition to the print mode (print processing in progress). At this time, the MFP 3 displays this message without using the Web browser 27 so as to reduce the load. Also, the MFP 3 obtains the job ID (print job ID) issued by the proxy APP 143 in step S3815 (
(Job Registration Processing and Job Information Return Processing)
In step S4514, the proxy APP 143 obtains job information which is registered in the job queue and corresponds to the designated job ID. In step S4515, the proxy APP 143 returns the job information obtained in step S4514 to the device. Then, this processing sequence ends (step S4517). In step S4516, since a job corresponding to the job ID is not present in the job queue of the target device, the proxy APP 143 returns a message indicating that job information is absent to the request source device (MFP 3 in this case). Then, this processing sequence ends (step S4517).
Note that
Note that a control system in which when the proxy APP 143 includes only one job queue, as shown in
Thus, even when the MFP cannot issue a job obtaining request to the proxy APP by designating a job using a job ID, a print request issued from the Web browser of the MFP to the document creation APP can be processed as a top priority print job. As a result, the MFP 3 can print that job without being interrupted by an external job, and a system excellent in the user's operability can be provided.
The third embodiment of the present invention will foe described below. The first embodiment has exemplified a print job, and this embodiment will exemplify a reading job. Note that a description about parts redundant to the first embodiment will not be repeated.
[Processing Sequence]
(Processing when MFP Issues Reading Instruction)
After completion of the print processing or reading processing, the MFP 3 notifies the proxy APP 143 of that information (step S3904). In step S3905, the proxy APP 143 executes job deletion processing shown in
As described in the first embodiment, the present invention has a purpose of executing a job issued when the user operates the Web browser 27 of the MFP 3 to have the top priority. For this purpose, when the MFP 3 issues a job obtaining request to the proxy APP 143 in step S3902, it designates an option to obtain only a job in a top priority job queue in the job queue shown in
In step S3907, the MFP 3 transitions to a mode for excluding an externally input job, and permitting only acceptance of a job notification, and the process advances to step S3908.
When the user designates an upload destination of a reading image file, and presses a selection button 754, the Web browser 27 displays the home window 742. At this time, the home window 742 is updated while the upload destination of the reading image file selected by the user is reflected to an upload destination display part 733 in the home window 742. When the user presses a reading button 734, the Web browser 27 issues a reading request to the reading APP 147 (step S3912). At this time, this reading request includes information indicating that a host which issued this reading request is the MFP (host=mfp), and information indicating that this reading request does not require any job notification to the MFP 3 (notification=no).
Upon acceptance of the reading request, the reading APP 147 issues a reading job to the cloud scan APP 148 (step S3913). At this time, the reading job includes information indicating that a host which issued the reading request of the reading job is the MFP (host=mfp), and information indicating that this reading request does not require any job notification to the MFP 3 (notification=no) according to the reading request received from the MFP 3. The cloud scan APP 148 inputs the reading job to a scan queue of the proxy APP 143 (step S3914). At this time, the cloud scan APP 149 further adds issued year/month/day/time information of the reading job to the reading job. The proxy APP 143 executes job registration processing shown in
The cloud scan APP 148 returns the job ID (reading job ID) returned from the proxy APP 143 to the reading APP 147. Furthermore, in response to acceptance of the job ID from the cloud scan APP 148, the reading APP 147 notifies the MFP 3 of information indicating that the reading job is issued. At this time, the reading APP 147 notifies the MFP 3 of the information to be notified including the job ID (reading job ID) returned from the cloud scan APP 148. This notification can be attained by utilizing, for example, the JavaScript® embedded in Web page information. At the issuance timing of the reading job, the Web browser 27 executes a Scan function, which is exported by the MFP 3 to the Web browser 27, via the JavaScript®.
When the Scan function is called, the MFP 3 receives information representing that the reading job is registered in the scan queue. At this time, the job ID (reading job ID) included in the received information is passed to the MFP 3 as an argument of the Scan function, and the MFP 3 also obtains the job ID (reading job ID) generated by the proxy APP 143 (step S3917). In this manner, since the MFP 3 includes the Scan function, and the Web browser 27 utilizes the Scan function via the JavaScript®, an unnecessary job notification can be omitted. As a result, reductions of the load on the server, the data traffic of the communication channel, and the data communication cost can be attained.
The MFP 3 issues a job (reading job) obtaining request to the proxy APP 143 (step S3918). The proxy APP 143 executes job information return processing (
[Example of Reading Job Information]
The MFP 3 obtains a storage destination of a reading setting file indicating reading settings and a temporary upload destination of a reading image file from the returned reading job information. A combination of the reading setting file and reading image file will be referred to as “reading data” hereinafter. Also, the reading setting file will also be referred to as a (reading) job ticket. The reading setting file is stored at a path (URI) designated by “ticketUri”, and the reading image file will be temporarily stored at a path (URI) designated by “temporaryUploadUri” by processing of step S3920 (to be described later). The reading setting file is stored in an HDD 202 in a PC 7. A temporary upload destination of a reading image file is prepared in a storage which can be utilized by the cloud scan APP 148. In this embodiment, a reading image file is stored in the HDD 202 in the PC 7. The MFP 3 displays a message representing a reading operation method like “set original, and then press start button” on the display unit 21, thus notifying the user of the reading operation method. At this time, the MFP 3 displays this message without using the Web browser 27.
When the user sets an original and presses a start button included in an operation unit 20, the MFP 3 obtains a reading setting file by accessing the path (URI) designated by “ticketUri”. The MFP 3 executes reading processing according to the contents of the reading setting file. Then, the MFP 3 uploads a reading image file generated by the reading processing to the path (URI) designated by “temporaryUploadUri”, and then notifies the proxy APP 143 of completion of the reading processing (step S3920). In step S3921, the cloud scan APP 148 uploads the reading image file temporarily stored at the path (URI) designated by “temporaryUploadUri” to a path (URI) designated by “uploadUri”. In step S3922, the cloud scan APP 148 executes job deletion processing (
After completion of the reading processing in step S3920, the Web browser 21 of the MFP 3 requests the reading APP 147 to transmit the home window 742 (step S3924). The reading APP 147 transmits information of the home window 742 to the MFP 3 in response to the request (step S3925). The MFP 3 displays the received home window 742 on the Web browser 27 (step S3924). Then, the MFP 3 waits for a user input operation (step S3926).
(Processing when Mobile Terminal Issues Reading Instruction)
When the user designates an upload destination of a reading image file, and presses a selection button 754, the Web browser 9 of the mobile terminal 14 displays the home window 742. At this time, the home window 742 is updated while the upload destination of the reading image file selected by the user is reflected to the upload destination display part 733. When the user presses the reading button 734, the Web browser 9 issues a reading request to the reading APP 147 (step S4006). At this time, this reading request includes information indicating that a host which issued this reading request is the mobile terminal (host=phone), and information indicating that this reading request requires a job notification to the MFP 3 (notification=yes).
Upon acceptance of the reading request, the reading APP 147 issues a reading job to the cloud scan APP 148 (step S4007). At this time, the reading job includes information indicating that a host which issued the reading request of the reading job is the mobile terminal (host=phone), and information indicating that this reading job requires a job notification to the MFP 3 (notification=yes). The cloud scan APP 148 inputs the reading job to the scan queue of the proxy APP 143 (step S4008). At this time, the cloud scan APP 148 further adds issued year/month/day/time information of the reading job to the reading job. The proxy APP 143 executes job registration processing (
In step S4008, the cloud scan APP 148 returns the job ID (reading job ID) returned from the proxy APP 143 to the reading APP 147. Upon reception of the response to the reading request issued to the reading APP 147, the Web browser 9 of the mobile terminal 14 requests the reading APP 147 to transmit a reading execution confirmation window (step S4011). The reading APP 147 transmits information of the reading execution confirmation window to the mobile terminal 14 in response to the request (step S4012). Then, the mobile terminal 14 displays the received reading execution confirmation window on the Web browser 9, and displays a message “execute reading by MFP” on the Web browser 9 (step S4011). Then, the mobile terminal 14 transitions to an upload completion waiting state (step S4013).
When the proxy APP 143 transmits a job (reading job) notification to the MFP 3 in step S4309 in
[Example of Reading Job Information]
The MFP 3 obtains a storage destination of a reading setting file indicating reading settings and a temporary upload destination of a reading image file from the returned reading job information. The reading setting file is stored at a path (URI) designated by “ticketUri”, and the reading image file will be temporarily stored at a path (URI) designated by “temporaryUploadUri” by processing of step S4017 (to be described later). A temporary upload destination of a reading image file is prepared in a storage which can be utilized by the cloud 3 can APP 148. In this embodiment, a reading image file is stored in the HDD 202 in the PC 7. The MFP 3 displays a message representing a reading operation method like “set original, and then press start button” on the display unit 21, thus notifying the user of the reading operation method. At this time, the MFP 3 displays this message without using the Web browser 27.
When the user sets an original and presses a start button included in the operation unit 20, the MFP 3 obtains a reading setting file by accessing the path (URI) designated by “ticketUri”. The MFP 3 executes reading processing according to the contents of the reading setting file. Then, the MFP 3 uploads a reading image file generated by the reading processing to the path (URI) designated by “temporaryUploadUri”, and then notifies the proxy APP 143 of completion of the reading processing (step S4017). Then, the MFP 3 transitions to an online standby state (step S4021). In step S4018, the cloud scan APP 148 uploads the reading image file temporarily stored at the path (URI) designated by “temporaryUploadUri” to a path (URI) designated by “uploadUri”. In step S4019, the cloud scan APP 148 executes job deletion processing (
Upon completion of the upload processing by the cloud scan APP 148 in step S4018, the Web browser 9 of the mobile terminal 14 is notified of that information via the reading APP 147 (
As described above, the present invention can be similarly applied to the reading job as in the print job in the first embodiment.
The first embodiment has exemplified the case in which the user operates a Web browser 27 of an MFP 3 to print a document opened by a document creation APP 145, as shown in
(Job Registration Processing)
When job registration processing is requested, in
In step S4203, the proxy APP 143 confirms the presence/absence of jobs in the top priority job queue in the job queue shown in
In step S4206, the proxy APP 143 obtains issued year/month/day/time data of the job as a registration target. In step S4207, the proxy APP 143 registers the job in the top priority job queue in an issued year/month/day/time order, and saves respective pieces of information in a table which is required to store job information and is shown in
In step S4209, the proxy APP 143 confirms a job type. If the proxy APP 143 determines that the job type is a print job (YES in step S4209), the process advances to step S4210; if it determines that the job type is another job type (reading job) (NO in step S4209), the process advances to step S4211. In step S4210, the proxy APP 143 registers the job at the bottom position of a general print queue in the job queue shown in
As described above, in addition to the effects of the first embodiment, a plurality of jobs successively issued by the MFP can be processed in a correct order.
The first to third embodiments have exemplified the case in which a document creation APP 145 or reading APP 147 notifies an MFP 3 of information indicating that a job has been issued. As another embodiment, in place of the case in which the document creation APP 145 (or reading APP 147) notifies the MFP 3 of information indicating that a job has been issued, a proxy APP 143 may issue a job notification to the MFP 3. At this time, the proxy APP 143 notifies the MFP 3 of the job notification including a job ID (print job ID or reading job ID). Thus, the MFP 3 need not wait for an elapse of an assumed time required for image conversion in step S3618 in
In this embodiment, processing after the proxy APP 143 executes job registration processing (step S3615 in
Upon reception of a job notification issued from the proxy APP 143, in
In step S4609, based on information added to the job notification, the MFP 3 confirms whether or not the job is that issued from a device, that is, it is a job, a host of which is the MFP (host=mfp). If the MFP 3 determines that the job is that issued from the device (NO in step S4610), the process advances to step S4604; otherwise (YES in step S4610), the process advances to step S4605.
In step S4606, the MFP 3 receives print job information or reading job information, and the process advances to step S4607. A description of the subsequent processes will not be given. Thus, in addition to the effects of the first embodiment, a processing waiting time can be reduced.
Still another embodiment according to the present invention will be described as the sixth embodiment. A case will be examined below wherein the user launches a document creation APP 145 or reading APP 147 from a Web browser 27 of an MFP 3 to make a print request operation or reading request operation, and the document creation APP 145 or reading APP 147 issues a job. In such case, it is expected that the MFP 3 surely obtains and processes the issued job.
In this embodiment, for example, in step S3619 in
In step S3617 in
The same applies to a reading job. In this case, a job ID is given with “scn”. Therefore, even when the reading APP 147 issues a reading job, the MFP 3 can surely receive that reading job and can execute reading processing, thus improving the user's operability.
The first embodiment has exemplified the case in which a user operation of a document creation APP 145 utilizing a Web browser 27 is temporarily not accepted during an interval from an operation in step S3612 until step S3624 in
In
In this “MFP dedicated mode”, the proxy APP 143 determines by adding a condition that limits a job range to a job, a host of which is the MFP (host=mfp) as a determination condition in step S4304 or S4307 in
Thus, when the proxy APP 143 is in the MFP dedicated mode of the target device (MFP 3 in this case), only a job issued from the document creation APP 145 or reading APP 147 when the user operates the Web browser 27 of the MFP 3 is processed.
After the proxy APP 143 transitions to the MFP dedicated mode in step S5204, processes of steps S3608 to S3616 are executed. During execution of these processes, the document creation APP 145 notifies the MFP 3 of information indicating that a print job has been issued. At this time, the document creation APP 145 notifies the MFP 3 of the information to be notified, which includes a job ID (print job ID) returned from a cloud print APP 146. This notification can be implemented by utilizing, for example, the JavaScript® embedded in Web page information.
When a print job is issued, the Web browser 27 executes a Print function, which is exported by the MFP 3 to the Web browser 27, via the JavaScript®. When the Print function is called, the MFP 3 receives information representing that the print job is registered in the print queue. At this time, a job ID (print job ID) included in the received information is passed to the MFP 3 as an argument of the Print function, and the MFP 3 also obtains the job ID (print job ID) generated by the print APP 143 (step S5205).
The MFP 3 saves a URL (Uniform Resource Locator) of a page (a home window of the document creation APP 145) to be displayed at the next launch timing of the Web browser 27 in a RAM 17, thus quitting the Web browser 27 (step S5205). Furthermore, in step S5205, upon reception of information indicating that the print job has already been issued, the MFP 3 displays a message indicating that execution of print-related processing is in progress like “in print preparation” or “print in progress” on the display unit 21. Then, the MFP 3 notifies the user of transition to a print mode (print processing in progress). At this time, the MFP 3 displays this message without using the Web browser 27. After that, processes of steps S3618 to S3623 are executed, and the process then advances to step S5206.
In step S5206, the MFP 3 launches the Web browser 27. Then, the Web browser 27 accesses the page (the home window of the document creation APP 145) designated by the URL saved in the RAM 17 in step S5205 to request the document creation APP 145 to transmit the home window. The document creation APP 145 transmits information of the home window to the MFP 3 in response to the request (step S5207). The MFP 3 displays the home window on the Web browser 27 (step S5206).
When the user presses a home button (not shown) of an operation unit 20 of the MFP 3, the MFP 3 quits the Web browser 27, and displays a home window of the MFP 3 on the display unit 21 (step S5208). The MFP 3 notifies the proxy APP 143 of information indicating that the Web browser 27 has been quit (step S5209). Upon reception of the notification indicating the Web browser has been quit from the MFP 3, the proxy APP 143 transitions from the MFP dedicated mode to the normal mode when the target device which processes a job is the MFP 3 (step S5210). Then, the MFP 3 waits for a user input operation (step S5211).
(Exclusive Control Cancel Processing)
The MFP 3 may execute the exclusive control cancel processing when a time-out is reached. For example, the document creation APP 145 monitors HTTP request intervals from the Web browser 27 of the MFP 3. Then, when an HTTP request from the Web browser 27 is not received for a certain time period (for example, 5 min), the document creation APP 145 notifies the MFP 3 of a time-out via the JavaScript® embedded in Web page information. More specifically, the Web browser 27 executes a Timeout function, which is exported by the MFP 3 to the Web browser 27, via the JavaScript®. When the Timeout function is called, the MFP 3 executes the exclusive control cancel processing shown in

Still another embodiment of the present invention will be described below. For example, when an MFP is a low-end one in which an operation unit 20 does not include any buttons required to make complicated operations, and no display unit 21 is included, a mobile terminal may be used in place of the operation unit 20 and display unit 21 in some cases. The following two cases are assumed as an example of such case.
Case 1: The mobile terminal and MFP are connected via USB (Universal Serial Bus) or the like
Case 2: The mobile terminal and MFP are connected via a wireless network.
In case 1, the MFP is registered in a cloud print service and cloud scan service via the mobile terminal. In this case, when a Web browser of the mobile terminal issues a print request to a document creation APP 145 or issues a reading request to a reading APP 147, it executes the same processing as the MFP 3 (Web browser 27) shown in
In case 2, when the document creation APP 145 or reading APP 147 is opened from the Web browser of the mobile terminal, each APP determines whether or not the mobile terminal is operated from the same place as that of the MFP. As this determination method, for example, a global IP address or MAC address of a router to which the mobile terminal is connected, and that of a router to which the MFP is connected are obtained. Then, when the two global IP addresses match, the configuration of case 2 can be determined. As another determination method, when the two MAC addresses match, the same place is determined. When it is determined that the mobile terminal is operated from the same place as the MFP, and when the Web browser of the mobile terminal issues a print request to the document creation APP 145 or issues a reading request to the reading APP 147, it executes the same processing as the MFP 3 (Web browser 27) shown in
In this manner, even when the MFP includes neither an operation unit including buttons required to make complicated operations nor the display unit 21, and when the mobile terminal is used in place of the operation unit and display unit, the present invention is applicable. As a result, in the same manner as in the operation of the Web browser 27 of the MFP 3, a print request or reading request issued from the Web browser of the mobile terminal can be processed with the top priority, thus assuring excellent user's operability.
The aforementioned embodiments assume a PC as an information processing apparatus. However, the present invention is not limited to this example, and it is applicable to an arbitrary information processing apparatus (terminal) (for example, a DVD player, game, set-top box, Internet home appliances, and the like), which allows a similar use method. Also, the aforementioned embodiments assume an MFP as a peripheral apparatus. However, the peripheral apparatus may be any of a copying machine, facsimile, scanner, digital camera, apparatus including these multi-functions, and the like.
The aforementioned embodiments have exemplified the Windows® OS as an OS. However, the present invention is not limited to this, and an arbitrary OS can be used. The aforementioned embodiments use Ethernet® as a network configuration example. However, the present invention is not limited to such specific example, and an arbitrary interface such as a wireless LAN, IEEE1394, Bluetooth®, or USB may be used. Also, functions in various applications (firmware), and some or all of processes related to the aforementioned flowcharts may be configured using dedicated hardware.
According to the aforementioned embodiments, even when a cloud system is used as a control system, it is easy to built the system and to implement applications, thus reducing development and management costs. Also, since no problem is posed for implementation of firmware for a low-performance printer or a low-end MFP like the MFP 3, and respective processes do not require long time, the user's operability can be improved.
An application which is used to print a document like the document creation APP 145 has been exemplified. However, the present invention is not limited to this. For example, the present invention may be applied to an application used to print a photo, that used to transmit or receive facsimile data, that which utilizes or controls other peripheral apparatuses, and the like.
Details of the processes in principal cases have been explained using the flowcharts shown in
Embodiments of the present invention can also be realized by a computer of a system or apparatus that reads out and executes computer executable instructions recorded on a storage medium (e.g., non-transitory computer-readable storage medium) to perform the functions of one or more of the above-described embodiment(s) of the present invention, and by a method performed by the computer of the system or apparatus by, for example, reading out and executing the computer executable instructions from the storage medium to perform the functions of one or more of the above-described embodiment(s). The computer may comprise one or more of a central processing unit (CPU), micro processing unit (MPU), or other circuitry, and may include a network of separate computers or separate computer processors. The computer executable instructions may be provided to the computer, for example, from a network or the storage medium. The storage medium may include, for example, one or more of a hard disk, a random-access memory (RAH), a read only memory (ROM), a storage of distributed computing systems, an optical disk (such as a compact disc (CD), digital versatile disc (DVD), or Blu-ray Disc (BD)™), a flash memory device, a memory card, and the like.
While the present invention has been described with reference to exemplary embodiments, it is to be understood that the invention is not limited to the disclosed exemplary embodiments. The scope of the following claims is to be accorded the broadest interpretation so as to encompass all such modifications and equivalent structures and functions.
