The CPU 11 reads out and loads the first registration program 13A from the storage unit 13 into the memory 12, and sequentially executes processes included in the first registration program 13A.
In addition, the wireless communication unit 18 according to the present exemplary embodiment is capable of wireless communication with the server 80 over the network N. In the wireless communication unit 18 according to the present exemplary embodiment, a communication standard such as what is called 4G or 5G is applied as the communication standard for communication with the server 80, but obviously the communication standard is not limited thereto.
Furthermore, the wireless communication unit 18 according to the present exemplary embodiment may also wirelessly communicate with the image processing device 90 directly. In the wireless communication unit 18 according to the present exemplary embodiment, Bluetooth (registered trademark) is applied as the communication standard for communication with the image processing device 90, but the communication standard is not limited thereto.

As illustrated in
The storage unit 93 according to the present exemplary embodiment is achieved with an HDD, an SSD, flash memory, or the like. A second registration program 93A and a printing program 93B are stored in the storage unit 93, which acts as a storage medium. The second registration program 93A and the printing program 93B are stored in the storage unit 93 by connecting the recording medium 97 with the programs written thereto to the media reading and writing device 96 and causing the media reading and writing device 96 to read out each program from the recording medium 97. The CPU 91 successively reads out and loads each of the second registration program 93A and the printing program 93B from the storage unit 93 into the memory 92, and sequentially executes processes included in each program.
Additionally, a virtual printer management information database 93C and a user management information database 93D are stored in the storage unit 93. Details about these databases will be described later.
On the other hand, the communication I/F unit 98 according to the present exemplary embodiment communicates with the server 80 over the network N.
Note that, although not illustrated in the drawings, the image processing device 90 obviously is provided with components such as a wireless communication unit that performs the wireless communication described above with the information processing device 10, an image processing engine for achieving the image printing function, and a scanner unit for achieving the image reading function.
Next,
The generation unit 91A according to the present exemplary embodiment generates, for each request, different device identification information according to the request.
In other words, as described above, the image processing system 1 according to the present exemplary embodiment is configured to provide a cloud print service, and when the cloud print service is used, a virtual printer corresponding to the image processing device 90 is created on the server 80. Also, when the cloud print service is used, an identifier referred to as a universally unique identifier (UUID) is typically set in correspondence with the image processing device 90. Accordingly, in the image processing system 1 according to the present exemplary embodiment, the identifier is applied as the above device identification information.
In addition, the registration unit 91B according to the present exemplary embodiment registers, in the server 80, a virtual printer virtually indicating itself for each of the generated device identification information (in the present exemplary embodiment, a UUID, hereinafter referred to as the “identifier”).
Also, in the case where multiple virtual printers are registered, the execution unit 91C according to the present exemplary embodiment executes polling, which is a process of periodically querying each of the multiple registered virtual printers. Furthermore, the usage limiting unit 91D according to the present exemplary embodiment uses user management information, in which users who are able to use each of the multiple virtual printers registered in the server 80 are registered, to narrow down the virtual printers that are usable by each user.
Note that in the present exemplary embodiment, authentication information for each virtual printer is registered in the user management information, and the usage limiting unit 91D allows a corresponding virtual printer to be used if a user is authenticated using the authentication information. Also, in the present exemplary embodiment, when a virtual printer is registered by the registration unit 91B, the user requesting the registration of the virtual printer is registered in the user management information as a user who is able to use the virtual printer.
Next,
The virtual printer management information database 93C according to the present exemplary embodiment is a database in which information related to the virtual printers described above is registered, and as illustrated in
The virtual printer name is information indicating a name of a virtual printer assigned to each virtual printer to specify the corresponding virtual printer. Also, the identifier is information indicating the identifier described above that is assigned to the corresponding virtual printer.
Next,
The user management information database 93D according to the present exemplary embodiment is a database in which information related to users of the image processing system 1 is registered, and as illustrated in
The user ID is preassigned information that is different for each user to individually identify the corresponding user. Also, the virtual printer name is the same information as the virtual printer name in the virtual printer management information database 93C, and the authentication information is preset information for authenticating the corresponding user.
Note that in the present exemplary embodiment, information that is different for each user is set as the authentication information, but the authentication information is not limited thereto, and the authentication information may also be set for each of predetermined groups, such as for each company or each division within a company, for example. Also, in the present exemplary embodiment, a pair of information identifying the user and a password is applied as the authentication information, but obviously the authentication information is not limited to this configuration.
Next,
First,
In the image processing system 1 according to the present exemplary embodiment, when an administrator of the image processing system 1 for each company that uses the shared office supplies input instructing the administrator’s own information processing device 10 to execute the first registration process, the CPU 11 of the information processing device 10 executes the first registration program 13A, thereby causing the first registration process illustrated in
In step 100 of
In step 104, the CPU 11 controls the display unit 15 to display a user information input screen having a predetermined configuration, and in step 106, the CPU 11 stands by until predetermined information is inputted.
As illustrated in
The user, who is an administrator, uses the input unit 14 to input information indicating the virtual printer name and the name and authentication information of each user who will be able to use the virtual printer into the corresponding input area 15A on the user information input screen, and then specifies a Finish button 15B. When the Finish button 15B is specified, a positive determination is return in step 106, and the flow proceeds to step 108.
In step 108, the CPU 11 transmits the information indicating the virtual printer name (hereinafter referred to as the “virtual printer name information”) and the name and authentication information of each user (hereinafter referred to as the “user information”) inputted on the user information input screen to the image processing device 90, and then ends the first registration process. Note that in step 108, the CPU 11 also includes the name and authentication information of the administrator him- or herself in the user information transmitted to the image processing device 90. At this point, information pre-registered separately by the administrator him- or herself or the like is used as the name and authentication information of the administrator.
Next,
In step 200 of
In step 204, the CPU 91 stands by until the virtual printer name information and user information described above is received, and in step 206, the CPU 91 stores (registers) information indicating the received virtual printer name information and generated identifier in the virtual printer management information database 93C. In step 208, the CPU 91 stores (registers) the received virtual printer name information and user information in the user management information database 93D, and then ends the second registration process.
By executing the first registration process and the second registration process above according to an instruction from the administrator of each company that uses the shared office, the virtual printer management information database 93C and the user management information database 93D illustrated by way of example in
Next,
In the image processing system 1 according to the present exemplary embodiment, when a user registered in the user management information database 93D uses a virtual printer to print, the user executes a dedicated application program installed in the user’s own information processing device 10. When executing the application program, the user inputs the user ID and authentication information set with respect to the user him- or herself. By executing the application program, a print job to be printed is held together with the user ID and authentication information inputted by the user in the corresponding virtual printer created on the server 80. Note that if the user uses a web browser application program installed in the user’s own information processing device 10 to access the server 80 and input the user ID and authentication information on a displayed screen for inputting the user ID and authentication, the virtual printer usable by the user may be displayed, and by selecting and giving a print instruction to the displayed virtual printer and uploading data to be printed, the print job to be printed may be held together with the user ID and authentication information inputted by the user in the corresponding virtual printer created on the server 80.
In the above state, the printing process illustrated in
In step 300 of
In step 304, the CPU 91 determines whether or not the virtual printer to be processed is holding a print job. If the determination is negative, the flow proceeds to step 318, whereas if the determination is positive, the flow proceeds to step 306.
In step 306, the CPU 91 acquires, from the virtual printer to be processed, the user ID and authentication information corresponding to the print job determined to be held in the virtual printer to be processed. In step 308, the CPU 91 reads out the authentication information corresponding to the acquired user ID from the user management information database 93D.
In step 310, the CPU 91 determines whether or not the authentication information acquired from the virtual printer to be processed matches the authentication information read out from the user management information database 93D, and thereby determines whether or not authentication is successful for the user performing the printing process with respect to the virtual printer to be processed. In the case of a positive determination result, the flow proceeds to step 312.
In step 312, the CPU 91 acquires the print job from the virtual printer to be processed, and in step 314, the CPU 91 executes the printing process on the basis of document data to be printed and print settings information included in the acquired print job. Thereafter, the flow proceeds to step 318.
On the other hand, if the determination in step 310 is negative, or in other words, if authentication is unsuccessful, the flow proceeds to step 316, and a predetermined authentication error process is executed. Thereafter, the flow proceeds to step 318. Note that in the present exemplary embodiment, a process of transmitting information indicating that authentication was unsuccessful to the information processing device 10 possessed by the user corresponding to the acquired user ID is applied as the above authentication error process, but obviously the authentication error process is not limited thereto.
In step 318, the CPU 91 determines whether or not the processes from steps 302 to 316 have been executed for all virtual printers for which information is included in the read-out virtual printer management information. If the determination is negative, the flow returns to step 302, whereas if the determination is positive, the printing process ends. Note that when repeating the process from steps 302 to 318, the CPU 91 treats a virtual printer that has not been processed yet as the virtual printer to be processed.
The overall configuration of the image processing system 1 according to the present exemplary embodiment and the hardware configurations of the information processing device 10 and the image processing device 90 are similar to the image processing system 1 according to the first exemplary embodiment, and consequently a description is omitted here.
First, a functional configuration in the control unit of the image processing device 90 according to the present exemplary embodiment will be described. In the functional configuration in the control unit of the image processing device 90 according to the present exemplary embodiment, only the operations of the execution unit 91C are different from the execution unit 91C according to the first exemplary embodiment.
Namely, the execution unit 91C according to the present exemplary embodiment narrows down the virtual printers to be polled according to a predetermined condition. More particularly, the execution unit 91C according to the present exemplary embodiment applies a condition specifying a virtual printer corresponding to a user who is present in the area where the image processing device 90 is installed (in the present exemplary embodiment, the shared office) as the above condition.
Hereinafter,
As illustrated in
Namely, in step 302A, the CPU 91 polls any one virtual printer for which information is included in the read-out virtual printer management information and which also matches a predetermined condition. In the present exemplary embodiment, as described above, a condition specifying a virtual printer corresponding to a user who is present in the shared office is applied as the predetermined condition.
In other words, in the shared office according to the present exemplary embodiment, the attendance of users who use the shared office and also use the image processing device 90 is managed by an attendance management system, and the attendance management system is capable of specifying a user who is present in the shared office. Furthermore, the image processing device 90 is connected to the attendance management system, and the image processing device 90 is also capable of specifying a user who is present in the shared office.
Accordingly, in step 302A, the CPU 91 uses the above attendance management system to specify the user ID of a user who is present in the shared office, and references the user management information database 93D to specify a virtual printer corresponding to the specified user ID. Thereafter, the CPU 91 polls only the specified virtual printer.
After that, in step 318A, the CPU 91 determines whether or not the processes from steps 302A to 316 have been executed for all virtual printers for which information is included in the read-out virtual printer management information and which also match the predetermined condition. If the determination is negative, the flow returns to step 302A, whereas if the determination is positive, the printing process ends. Note that when repeating the process from steps 302A to 318A, the CPU 91 treats a virtual printer which matches the predetermined condition and which has not been processed yet as the virtual printer to be processed.
Note that although the present exemplary embodiment describes a case of applying a condition specifying a virtual printer corresponding to a user who is present in the area where the image processing device 90 is installed as the predetermined condition, the predetermined condition is not limited to the above configuration. For example, a condition specifying a virtual printer narrowed down according to frequency of use may also be applied as the predetermined condition. As one configuration example for the above case, a history of printing using the image processing device 90 by each of the companies that use the shared office is recorded, weekdays and time periods with a high frequency of use are estimated, and the virtual printers to be polled are narrowed down for each company according to the frequency of use.
Also, the present exemplary embodiment describes a case of using an attendance management system to specify a user who is present in the shared office, but the configuration is not limited thereto. For example, a user who is present in the shared office may also be specified by monitoring communication packets on a network such as a LAN set up in the shared office.
The overall configuration of the image processing system 1 according to the present exemplary embodiment and the hardware configurations of the information processing device 10 and the image processing device 90 are similar to the image processing system 1 according to the first exemplary embodiment, and consequently a description is omitted here.
First, a functional configuration in the control unit of the image processing device 90 according to the present exemplary embodiment will be described. In the functional configuration in the control unit of the image processing device 90 according to the present exemplary embodiment, only the operations of the execution unit 91C are different from the execution unit 91C according to the first exemplary embodiment.
Namely, the execution unit 91C according to the present exemplary embodiment narrows down the virtual printers to be polled according to a predetermined condition. In particular, the execution unit 91C according to the present exemplary embodiment applies a condition specifying a virtual printer corresponding to a user who is logged in to the virtual printer itself as the above condition.
Hereinafter,
In the present exemplary embodiment, when a user uses a usable virtual printer, the user logs in to the image processing device 90 using the user ID and authentication information set with respect to the user him- or herself, and uses the application program described above to perform desired printing. With this arrangement, a print job corresponding to the above printing is held in the corresponding virtual printer.
The CPU 91 of the image processing device 90 according to the present exemplary embodiment executes the printing program 93B when the user logs in as above, thereby causing the printing process illustrated in
In step 350 of
In step 352, the CPU 91 determines whether or not the authentication information inputted during login matches the read-out authentication information, and thereby determines whether or not authentication is successful for the user performing the printing process with respect to the virtual printer. In the case of a positive determination result, the flow proceeds to step 354.
In step 354, the CPU 91 specifies a virtual printer to be processed (hereinafter referred to as the “specific virtual printer”) by reading out the virtual printer name corresponding to the user ID inputted during login from the user management information database 93D. Additionally, the CPU 91 reads out the identifier corresponding to the specific virtual printer from the virtual printer management information database 93C.
In step 356, the CPU 91 uses the read-out identifier to poll the specific virtual printer. In step 358, the CPU 91 acquires the print job from the specific virtual printer, and in step 360, the CPU 91 executes the printing process according to the acquired print job. Thereafter, the printing process ends.
On the other hand, if the determination in step 352 is negative, or in other words, if authentication is unsuccessful, the flow proceeds to step 362, and a predetermined authentication error process is executed. Thereafter, the printing process ends. Note that in the present exemplary embodiment, a process of transmitting information indicating that authentication was unsuccessful to the information processing device 10 possessed by the user corresponding to the acquired user ID is applied as the above authentication error process, but obviously the authentication error process is not limited thereto.
Note that although the exemplary embodiments above describe a case of applying the present disclosure to a cloud print service, the configuration is not limited thereto. For example, the present disclosure may also be applied to a print service that does not use a cloud server, such as a print service that uses a network server or the like inside an organization, for example.
Also, the exemplary embodiments above describe a where the virtual printer management information database 93C and the user management information database 93D are registered in the image processing device 90, but the configuration is not limited thereto. For example, each database may also be registered in a device accessible by the image processing device 90, such as the server 80.
Moreover, although the exemplary embodiments above describe a case of applying a cloud print service as an example of an image processing service according to the present disclosure, the image processing service is not limited thereto. For example, a service that executes a process of altering or transferring image data may also be applied as the image processing service. A virtual image processing device corresponding to the functions provided in the image processing device 90, such as the image reading function and the image transmitting function provided in the image processing device 90, may also be registered in the server 80. For example, in the case where a virtual character recognition device is registered as the virtual image processing device, it is possible to transmit image data read by the image processing device 90 to the virtual character recognition device and perform a character recognition process on the image data in the server 80, while during this time, the image processing device 90 polls the virtual character recognition device, and when a character recognition result is generated, the image processing device 90 acquires the generated character recognition result.
