The present disclosure relates to a management system, a client terminal, a control method, and a storage medium for performing printing in a public space.
In recent years, a print system using a cloud print service in which a print job is transmitted from a personal computer (PC) to an image forming apparatus via a cloud and printing is performed for the print job has started to be widely used. In such a print system, first, an administrator registers an image forming apparatus, as a device, in a tenant of the cloud print service to which the administrator belongs. The administrator sets whether the image forming apparatus is allowed to be used, for each user belonging to the tenant. The tenant refers to a service system deployed on a cloud by a user, and has an access-restricted storage area dedicated to a registered user. For example, in a company-A tenant of the cloud print service used in a company A, an employee of the company A is registered as a user and an image forming apparatus of the company A is registered. The user of the company A can thereby perform printing using any image forming apparatus registered in the company-A tenant, by inputting a print job to the company-A tenant from a terminal in the company A.
Meanwhile, because of diversification of ways of working, there is a demand for printing a document stored in a client terminal, using an image forming apparatus installed in a public space such as a convenience store, a library, or a station.
To meet the demand, a cloud print service for printing in a public space has also been widely used. This is a cloud print service using a configuration generally called a public cloud and has, for example, a public print tenant. Such a cloud print service will be referred to as a “public print service”. In the public print service, user management based on the public print tenant can be performed, or a guest print function can be provided regardless of the presence or absence of user management. An image forming apparatus for printing in a public space is registered in the public print tenant and managed.
Further, it is conceivable that not only a conventional office but also a shared office and a coworking space are used because of the acceleration of use of telework, and a user who wants to perform printing is to perform printing using an image forming apparatus installed in a shared office. There are also provided space matching services in which, when using these stores, a user searches for a store beforehand, makes a reservation, uses the store, and pays a fee corresponding to a use time of the user. In these services, a store entry time and a store exit time of the user are managed to determine the use time of the user.
The following two types are mainly conceivable as a print method using the public print service in a shared office or a coworking space. The first type is a first method in which, after a job is input to the public print service, user authentication is performed and then an output is produced based on an execution instruction for the job using an image forming apparatus. The second type is a second method in which an image forming apparatus is designated as an output destination when a job is input to the public print service, and the image forming apparatus immediately executes the job upon receiving the job.
Japanese Patent Application Laid-Open No. 2006-251863 discusses a method related to the above-described second method. According to the method discussed in Japanese Patent Application Laid-Open No. 2006-251863, when a print instruction is issued on a client terminal, a network address is extracted from each of an Internet Protocol (IP) address of an image forming apparatus selected by a user and an IP address of the client terminal, and whether the addresses are both within the same network range is determined. In a case where these addresses are not within the same network range, the user is warned to select an image forming apparatus again. This can prevent an output from an image forming apparatus not intended by the user.
With the above-described first method, a user operation for issuing a print execution instruction is performed using the image forming apparatus to be the output destination, and thus there is such an advantage that the image forming apparatus to be the output destination can be reliably identified. Meanwhile, with the second method, there is such an advantage that a job input instruction and a print execution instruction are issued at the same time on a client terminal. However, with the second method, an image forming apparatus is to be designated as an output destination in advance, and thus, if a user makes a mistake in designating an image forming apparatus as the output destination, an output can be produced by an image forming apparatus not intended by the user.
In the case of printing using the public print service, it is also conceivable that a job is input using a public line or a network line different from a network in a store. For this reason, a client terminal and an image forming apparatus in the same store are not necessarily within the same network range. Thus, in a case where the above-described method discussed in Japanese Patent Application Laid-Open No. 2006-251863 is applied to printing using the public print service, there is a possibility that a print job input from a client terminal cannot be executed in an image forming apparatus in the same store.
In addition, image forming apparatuses installed in a plurality of shared offices and co-working spaces are registered in the public print service. If a user is enabled to select an image forming apparatus as the output destination based on the network range as discussed in Japanese Patent Application Laid-Open No. 2006-251863, an image forming apparatus installed outside the store can be designated by mistake. In a case where the user makes a mistake in selecting an image forming apparatus as the output destination and an output product is produced by an image forming apparatus in another store, it is difficult to collect the output product as compared with a case where an output product is produced by an image forming apparatus in the office, and there is also an issue where such a mistake can lead to an information leakage.
Embodiments of the present disclosure are directed to a mechanism that enables a user to issue a print instruction from a client terminal after appropriately selecting an image forming apparatus, in a public print service.
According to embodiments of the present disclosure, a management system configured to communicate with a client terminal via a network and provide a store management service includes one or more memories storing a set of instructions, and one or more processors that execute the set of instructions to perform login processing for a user of the client terminal to log in to the management service, based on a login request from the client terminal, acquire store entry and exit information about the user, and provide the client terminal with information about one or more print apparatuses installed in a store that the user has entered, based on the acquired store entry and exit information.
Further features of the present disclosure will become apparent from the following description of exemplary embodiments with reference to the attached drawings.
Exemplary embodiments of the present disclosure will be described below with reference to the drawings.
A space matching service (hereinafter referred to as an SMS) 103 is a management system that provides a store management service, including searching for a store to be used, and making a reservation for the store, and paying a fee corresponding to a time during which the store is used. A client terminal and image forming apparatuses are present in each of a store A and a store B that can be used from the SMS 103. More specifically, a client terminal 111 and image forming apparatuses 102a and 102b are in the store A, and a client terminal 121 and image forming apparatuses 122a and 122b are in the store B.
The SMS 103 provides a print function in cooperation with a cloud print service (hereinafter referred to as a CPS) 150, receives a print job from a client terminal 101, and saves the received print job. Furthermore, the SMS 103 transmits job information to the CPS 150. The CPS 150 receives a request for a print job from the image forming apparatus 102a, 102b, 122a, or 122b, and transmits the print job to the corresponding image forming apparatus. The CPS 150 is a print system that provides a print service. Each of the image forming apparatuses 102a, 102b, 122a, and 122b performs printing upon receiving the print job from the CPS 150.
Similarly, a print job can also be transmitted from the client terminal 111 in the store A or the client terminal 121 in the store B to the SMS 103.
The SMS 103, the CPS 150, the client terminal 101, the client terminal 111 and the image forming apparatuses 102a and 102b in the store A, and the client terminal 121 and the image forming apparatuses 122a and 122b in the store B are communicatively connected via the Internet. In the present exemplary embodiment, the SMS 103 mainly providing the functions such as making a reservation for a store and the CPS 150 mainly providing the print function are described as different services, but one service that provides the functions of both of the services may be used. Further, in the present exemplary embodiment, the SMS 103 is configured to provide a print job input screen, but the CPS 150 may provide this screen, or either of these services may provide a function and a screen to be used for printing.

<Check-In and Check-Out at Shop>
In step S501, the user inputs a user ID and a password and issues a login execution instruction, so that the client terminal 101 performs processing for logging in to the SMS 103.
In step S502, the user scans the two-dimensional barcode for store entry provided in the store, so that the client terminal 101 reads a store ID, as store information, from information in the barcode.
In step S503, the client terminal 101 transmits a check-in request (a store entry request) with the user ID and the store ID for check-in, to the store management unit 307 of the SMS 103.
In step S504, the store management unit 307 performs check-in processing for the user. The check-in processing is recorded in current store entry information such as store entry information 600 illustrated in
In step S505, the store management unit 307 transmits a check-in processing completion notification to the client terminal 101.
In step S506, the client terminal 101 transmits a check-out request (a store exit request) and the user ID for check-out, to the store management unit 307 of the SMS 103.
In step S507, the store management unit 307 performs check-out processing for the user. In the check-out processing, the store ID 602 and the store entry time 603 are deleted. In other words, the association between at least the identification information about the user and the identification information about the store that the user has entered, which is managed as the current store entry information, is canceled. However, these pieces of information and use history data about when and which store has been used by the user, with the exit time added thereto may be separately held for payment of a fee and confirmation of the use history of the user.
In step S508, the store management unit 307 transmits a check-out processing completion notification to the client terminal 101.
The check-in and check-out processing performed by reading, using the client terminal, the two-dimensional barcode provided by the store has been described above with reference to
<Print Processing>
In step S701, the user inputs a user ID and a password and issues a login execution instruction, so that the client terminal 101 issues a login request to the SMS 103. Upon receiving the login request from the client terminal 101, the SMS 103 performs login processing. In step S702, when an operation for starting the print processing is performed by the user, the client terminal 101 issues a print screen display request to the SMS 103, so that a print job input screen 1000 illustrated in
When the “print immediately” button 1002 is pressed, then in step S704, the client terminal 101 notifies the SMS 103 of a “print immediately” instruction request. In step S705, upon receiving the “print immediately” instruction request, the SMS 103 acquires the store entry information 600 about the logged-in user. In step S706, the SMS 103 generates a list of printers in the store from the printer list 902, by referring to the store ID 602 of the store entry information 600 acquired in step S705 and referring to the store printer management information 900 in which the store ID 602 is identical to the store ID 901. In step S707, the SMS 103 displays a printer selection screen 1010 as illustrated in
In response to the login processing in step S701, the store entry information 600 about the logged-in user may be acquired (in step S705) and further, the list of printers in the store may be generated (in step S706). Alternatively, in response to the print screen display in step S702, the store entry information 600 about the logged-in user may be acquired (in step S705) and further, the list of printers in the store may be generated (in step S706). Moreover, in steps S706 and S707, the information about printers in the store may be provided from the SMS 103 to the client terminal 101, and the list of printers in the store may be generated in the client terminal 101.
Instead of the printer selection screen 1010, a printer selection screen 1020 illustrated in
In step S708, the client terminal 101 uploads the file selected in step S703 to the SMS 103, and transmits a print execution request to the SMS 103 together with the printer ID corresponding to the printer name selected on the screen illustrated in
In step S709, upon receiving the print execution request, the SMS 103 determines whether the printer corresponding to the printer ID transmitted from the client terminal 101 is in the store. To be more specific, the SMS 103 confirms whether the transmitted printer ID is in the printer list generated in step S706. To perform strict determination, the SMS 103 may perform the processing in steps S705 and 706 again, generate a printer list at the time of print execution, and perform the determination.
If the SMS 103 determines that the printer is in the store in step S709, the processing proceeds to step S710. If the printer is not in the store, the user is notified of this result and printing is canceled. In step S710, the SMS 103 transfers the print data (the file) received in step S708 to the CPS 150. When transferring the print data, the SMS 103 attaches a parameter (push) indicating that printing is to be performed immediately and the printer ID to the print data. In step S711, upon receiving the transmitted file, the CPS 150 generates a print job based on the received file and saves the generated print job. In step S712, when detecting the job with the push parameter attached thereto through periodical job monitoring of the CPS 150, event notification, or the like, the image forming apparatus 102a transmits a job acquisition request to the CPS 150. In step S713, upon receiving the job acquisition request, the CPS 150 transmits the job to the image forming apparatus 102a. In step S714, the image forming apparatus 102a performs output processing on the transmitted print job.
In step S715, the SMS 103 saves the information about the selected printer that has performed printing, as printer last value information 800 illustrated in
In step S716, the client terminal 101 uploads the file selected in step S703 to the SMS 103. In step S717, upon receiving the file, the SMS 103 transmits the received file to the CPS 150. At this time, the SMS 103 transmits the received file together with a parameter (pull) indicating that a print job is to be held. In step S718, the CPS 150 generates a print job from the received file and saves the generated print job. The print job saved at this time does not have the push parameter attached thereto, and thus is not to be acquired by step S712, and an output is produced for the job when a print instruction is expressly issued by the user who has logged into the image forming apparatus 102a.
In step S1101, the SMS 103 determines which event is received. More specifically, the SMS 103 determines which one of the “print immediately” button 1002, the “upload” button 1003, and the “cancel” button 1004 illustrated in
In step S1102, the SMS 103 acquires the store entry information 600 about the user. In step S1103, the SMS 103 determines whether the user has entered a store, by referring to the store entry information 600 about the user to determine whether a value is held in the store ID 602. In a case where the user has entered a store (YES in step S1103), the processing proceeds to step S1104. In a case where the user has not entered a store (NO in step S1103), the processing proceeds to step S1115. In step S1115, the SMS 103 transmits a notification that printing is not possible because the user has not entered a store. In step S1104, the SMS 103 acquires the store printer management information 900 having the store ID 901 identical to the store ID 602. In step S1105, the SMS 103 acquires the printer list 902 from the store printer management information 900. In step S1106, the SMS 103 generates the printer selection screen 1010 illustrated in
In step S1107, the SMS 103 transmits the printer selection screen generated in step S1106 to the client terminal 101 to display this screen.
In step S1108, the SMS 103 determines whether a print execution request is received as an event based on an operation performed on the printer selection screen 1010. When the “OK” button 1012 is pressed, the SMS 103 determines that a print execution request is received (YES in step S1108) and the processing proceeds to step S1109. When the “cancel” button 1013 is pressed, the SMS 103 determines that a print cancel event is received (NO in step S1108) and the processing proceeds to step S1116. In step S1109, the SMS 103 saves the file received with the print execution request. In step S1110, the SMS 103 determines whether the image forming apparatus corresponding to the received print execution request is in the store, by determining whether the printer ID included in the parameter of the print execution request is included in the printer list 902 acquired in step S1105. In a case where the image forming apparatus is in the store (YES in step S1110), the processing proceeds to step S1111. In a case where the image forming apparatus is not in the store (NO in step S1110), the processing proceeds to step S1116. At this time, instead of the processing proceeding to step S1116 to cancel printing, job upload may be performed or the printer selection screen may be displayed again so that the image forming apparatus as the output destination can be selected again. In step S1111, the SMS 103 transmits the print file to the CPS 150 together with the parameter (push) indicating that printing is to be performed immediately. In step S1112, the SMS 103 associates the information about the image forming apparatus that has performed printing with the user ID 801 as the printer last value information 800, and saves the last used printer name 802 and the last used printer ID 803.
In step S1113, the SMS 103 saves a file received with a job upload request. In step S1114, the SMS 103 transmits the saved file to the CPS 150 together with the parameter (pull) indicating that the print file is to be held.
In step S1116, the print processing is canceled, and the processing ends.
As described above, in the present exemplary embodiment, the SMS 103 provides the list of print apparatuses installed in the store that the user has entered, based on the store entry and exit information about the user logging in to the SMS 103, to the client terminal 101. This makes it possible to, in a case where the user inputs a print job and simultaneously designates a print apparatus as an output destination, prevent the print job from being executed by a print apparatus outside the store.
In the first exemplary embodiment described above, the SMS 103 provides the list of print apparatuses installed in the store that the user has entered, based on the store entry and exit information about the user logging in to the SMS 103, to the client terminal 101.
In a second exemplary embodiment, an example in which the printer last value information 800 illustrated in
As described above, the printer last value information 800 illustrated in
