Description

  The present invention relates to a technique for performing print output after a print job is once stored in a server apparatus and receiving a print instruction for the print job, and in particular, an image forming apparatus capable of print output according to the characteristics of the print job. The technology is limited.

  The print job created on the client PC is not printed immediately, but is temporarily stored in the server device, and after receiving a print instruction from an image forming apparatus such as a multifunction peripheral, the print job stored in the server device is acquired. A printing system that performs a printing process is known.

  In this printing system, a print job is stored in association with user information, print data that can be printed by a user who has logged in to the multifunction device is displayed in a list on the operation screen of the multifunction device, and the actual print data is displayed from the displayed print data. In some cases, print data to be printed out is selected and print execution is instructed.

  When such a mechanism is adopted, in order to print out a print job, it is necessary to go to the multifunction device and give a print instruction on the spot. This can reduce the risk of information leakage due to leaving print data.

  Also, in such a printing system, it is often possible to print only a user's print job corresponding to the user who is logged in to the multifunction peripheral, and the print job stored by himself / herself is printed by another person. This can be suitably prevented.

  However, when a highly confidential document is printed by such a mechanism, it is necessary to further consider security. For example, when performing login processing to a multifunction device, authentication is often performed using an IC card, and if the IC card is lost, it is highly confidential to the user who obtained the IC card illegally. This is because the print job may be printed.

  Therefore, Patent Document 1 discloses an invention for determining whether or not a print job can be printed according to a score calculated as a result of performing a plurality of authentication processes.

Loads the program into the RAM 302 and executes this processing according to the control by the loaded program. The processing shown in steps S621 to S628 is processing performed by the CPU 201 of the authentication server 102, and a program for causing the CPU 201 of the authentication server 102 to execute this processing is stored in the external memory 211 of the authentication server 102. When executing this process, the CPU 201 loads the program into the RAM 202 and executes the process according to the control by the loaded program.

  First, the CPU 301 of the multi-function peripheral 103 acquires authentication information used for authentication of a user who uses the multi-function peripheral from an IC card placed on the card reader 319 (step S601). For example, a card ID for uniquely identifying the IC card is acquired from the IC card. Of course, it is possible to accept an input of a user ID and a password as authentication information via the operation unit 308 without using an IC card.

  Thereafter, the CPU 301 of the MFP 103 transmits the authentication information acquired in step S601 to make an authentication request for the user to the authentication server 102 (authentication request transmission: step S602).

  When receiving the authentication request from the multifunction device 103 (step S621), the CPU 201 of the authentication server 102 determines whether the card ID included in the authentication information received from the multifunction device 103 is registered in the user authentication table shown in FIG. Determination is made (step S622).

  Here, an example of the data configuration of the user authentication table 900 stored and managed in the external memory 211 of the authentication server 101 will be described with reference to FIG.

  As shown in FIG. 9, the user authentication table 900 includes data items such as a card ID 901, a user name 902, a password 903, and a security setting 904.

  The card ID 901 is a data item in which identification information for uniquely identifying an IC card is registered. The user name 902 is a data item in which the user name of the user who is the holder of the IC card having the card ID registered in the card ID 901 is registered. The password 903 is a data item in which password information used to log in to the multifunction machine 103 when the user forgets or loses the IC card is registered.

  The security setting 904 is a data item for registering information on what security level a user managed by each record can print on each multifunction device. The security level is set for each device group managed by the device group management table 1000 in FIG.

  From the MFPs belonging to the device group whose numerical value is “1”, the user prints all print jobs of “Top Secret (1)”, “Secret (2)”, and “Normal Document (3)”. Is possible. From the MFPs belonging to the device group whose numerical value is “2”, the user can print a print job that is “confidential (2)” and “regular document (3)”. ) "Security level cannot be printed. Similarly, only a print job having a security level of “normal document (3)” can be printed from a multi-function peripheral belonging to a device group having this numerical value “3”, and “confidential (1)”, “confidential” (2) "security level document cannot be printed. The above is an example of the data configuration of the user authentication table 900 of FIG.

  Here, an example of the data configuration of the device group management table 1000 stored and managed in the external memory 211 of the authentication server 102 will be described with reference to FIG. For example, grouping is performed based on the installation location of the multifunction peripheral, and the group is managed by the device group management table 1000.

  As shown in FIG. 10, the device group management table 1000 includes data items such as a device group No. 1001 and an associated multifunction device IP address 1002 as data items.

  Device group No. 1001 is a data item in which identification information for uniquely identifying a device group is registered.

  The assigned multifunction device IP address 1002 is a data item in which the IP addresses of multifunction devices belonging to the group are registered. For example, “,” is registered as a delimiter for the IP addresses of all the MFPs belonging to each group.

  Needless to say, other information may be used instead of the IP address as long as the information can identify the multifunction device. The above is the description of the data configuration of the device group management table 1000.

  In the present invention, the security setting 904 of the authentication table 900 of FIG. 9 and the object of the present invention of FIG. 10 are configured in such a manner that the IC card is acquired when the IC card is lost or the like. The purpose is to prevent users from printing confidential documents, and by limiting the number of MFPs that can print confidential documents, the possibility of printing confidential documents to others is reduced. It is possible. Note that it is desirable to limit multifunction devices capable of printing confidential documents to multifunction devices near the user's seat.

  Returning to the description of FIG. If the CPU 201 of the authentication server 102 determines in step S622 that the card ID included in the authentication request received from the multi-function peripheral 103 is not registered in the user authentication table 900 (NO), the process proceeds to step S622. Proceeding to S627, authentication result information of authentication NG is created.

  On the other hand, if the CPU 201 of the authentication server 102 determines in step S602 that the card ID received from the multi-function peripheral 103 is registered in the user authentication table 900, the process proceeds to step S623. The IP address of the MFP 103 that has made the request is acquired.

  Thereafter, the CPU 201 of the authentication server 102 searches the device group management table 1000 in FIG. 10 based on the IP address acquired in step S623, and acquires the device group to which the MFP having the IP address belongs (step S624). ). Then, the security level of the device group of the user holding the card ID acquired in step S621 is acquired (step S625). Thereafter, authentication OK authentication including the user information (user name, etc.) registered in the record in which it is determined that the card ID received in the determination process in step S622 is registered, and the security level acquired in step S625. Result information is created, and the process proceeds to step S628.

  In step S628, the CPU 201 of the authentication server 102 transmits the authentication result information created in step S626 or step S627 to the multi-function peripheral 103 that has issued the authentication request.

  When receiving the authentication result information from the authentication server 102 (step S603), the CPU 301 of the MFP 103 determines whether the authentication has succeeded (authentication OK) or has failed (authentication NG) (step S604). If it is determined in this determination process that the authentication is successful (authentication OK), user information included in the authentication result information is acquired (step 605), and a user login process indicated by the user information is performed (step S606). ). As a result, the user who operates the multi-function peripheral 103 is specified.

  On the other hand, if it is determined in the determination process in step S604 that the authentication has failed (NO), the CPU 301 advances the process to step S607 and displays an authentication failure screen (not shown) on the LCD display unit of the operation unit 308. This process is terminated. The above is the description of the user authentication process in FIG.

  The multifunction device 103 can perform print processing of a print job managed by the print management server 101 in accordance with an operation instruction of a user who operates the multifunction device 103 after the user login process is completed.

  At that time, the CPU 301 of the multifunction peripheral 103 first requests a list of print jobs that can be printed out by the logged-in user using the multifunction peripheral. Then, the print job list is displayed on the LCD display unit of the operation unit 308. Then, selection of a print job to be actually printed out is accepted from the print job list. Thereafter, in response to transmitting the selection information to the print management server 101, a print job transmitted from the print management server 101 is received, and print processing based on the received print job is executed.

  Hereinafter, a print job list request process performed by the MFP 103 and the print management server 101 will be described with reference to FIG. 7, and a print process performed by the MFP 103 and the print management server 101 will be described with reference to FIG.

  FIG. 7 is a flowchart illustrating print job list request processing performed by the CPU 301 of the multifunction peripheral 103 and the CPU 201 of the print management server 101. In the figure, the processes shown in steps S701 to S703 are processes performed by the CPU 301 of the multifunction machine 103, and a program for causing the CPU 301 to execute the processes is stored in the HDD 304. Loads the program into the RAM 302 and executes this processing according to the control by the loaded program. The processing shown in steps S721 to S724 is processing performed by the CPU 201 of the print management server 101. A program for causing the CPU 201 of the print management server 101 to execute this processing is stored in the external memory 211 of the print management server 101. When the processing is executed, the CPU 201 loads the program into the RAM 202 and executes the processing according to control by the loaded program.

  When the CPU 301 of the multi-function peripheral 103 receives a print job list display instruction in response to an operation instruction of a user who operates the multi-function peripheral, the CPU 301 transmits a print job list request to the print management server 101 (step S701). At that time, the user information (user name, etc.) of the user who is logged in to the multifunction device 103 and the security level of the logged-in multifunction device 103 are transmitted.

  When a print job list request is received from the MFP 103 of the print management server 101 (step S721), the bibliographic information table is searched, and the MFP 103 that made the request among the print jobs of the login user of the MFP 103 receives the request. A print job that can be printed out is acquired using the security level of the multifunction peripheral and the security level of the print job (step S722).

  After that, the print job list information acquired in step S722 is created (step S723), and the created print job list information is transmitted to the requesting MFP 103 (step S724).

  When receiving the print job list information (step S702), the CPU 301 of the multi-function peripheral 103 displays the print job list screen shown in FIGS. 13 and 14 (step S703). The above is the description of the print job list request process.

  Here, the print job list display screen 1300 displayed on the LCD display unit of the operation unit 308 of the MFP 103 in step S703 of FIG. 7 will be described with reference to FIGS.

  FIG. 13 is a diagram showing an example of the configuration of the print job list display screen 1300. As shown in FIG. 13, the print job list display screen 1300 includes a login user display unit 1301, a print job list display unit 1302, a print job selection unit 1303, a selection release button 1304, a print button 1305, and the like.

  The login user display unit 1301 is a display unit that displays a user name of a user who is logging in to the multifunction machine 103. The print job list display unit 1302 is a display unit that displays a list of print jobs that are acquired from the print management server 101 and can be printed out by the login user using the MFP. As information about the print job, a print job name 1302-1, print setting 1302-2, paper size 1302-3, page number 1302-4, time stamp 1302-5, and the like are displayed. The display items are not limited to these.

  A print job selection unit 1303 is used to select a print job instructing print output. When the print job checked by the print job selection unit 1303 receives an instruction to press the print button 1305, the print job is determined as a print job to be printed.

  A print cancel button 1304 is a button used to cancel all print job selections in the print job selection unit 1303. A print button 1305 is a button used to issue a print instruction for the print job selected by the print job selection unit 1303. The above is the description of the print job list display screen 1300.

  Note that FIG. 13 shows that “USER001” in the user authentication table 900 of FIG. 9 is assigned to the device group 03 when the bibliographic information table 1200 provisioned by the print management server 101 is in the state shown in FIG. An example of a print job list display screen displayed when logging in to a multifunction machine to which the machine belongs is shown.

  From the multifunction peripheral of the device group 03, USER001 can print all print jobs of “Top Secret (1)”, “Secret (2)”, and “Normal Document (3)”. Of the print jobs managed in the bibliographic information table shown in FIG. 12, USER001 print jobs are jobs whose job IDs are “J001”, “J002”, “J003”, and “J005”.

  Since USER001 can print all security level print jobs from the logged-in multifunction peripheral, a list of print jobs as shown in FIG. 13 is displayed.

  FIG. 14 shows an example of a print job list screen 1300 that is displayed when USER001 is logged in to the MFP 103 belonging to the device group 001 or device group 002.

  As shown in FIG. 9, the security level of the device group 01 and the device group 02 of USER001 is “3”, and USER001 prints out only “normal document (3)” from the multifunction peripherals belonging to them. A print job having a security level of “Top Secret (1)” or “Secret (2)” cannot be printed out.

  Therefore, when USER001 is logged in to the MFP 103 belonging to the device group 01 or the device group 02, the security level of the USER001 print job stored in the bibliographic information table of FIG. Only the print jobs with the job IDs “J001” and “J005”, which are “document (3)”, are displayed on the print job list display unit 1302.

  By configuring in this way, it is not possible to issue print instructions for print jobs that cannot be printed with the security level of each multifunction device from each multifunction device, thereby enabling print output according to the security level of the print job. It is possible to limit the number of multifunction devices.

  Next, a printing process performed by the multifunction machine 103 and the print management server 101 will be described with reference to FIG.

  FIG. 8 is a flowchart illustrating print processing performed by the CPU 301 of the multifunction peripheral 103 and the CPU 201 of the print management server 101. In the figure, the processing from step S801 to step S806 is processing performed by the CPU 301 of the multi-function peripheral 103, and a program for causing the CPU 301 to execute the processing is stored in the HDD 304. Loads the program into the RAM 302 and executes this processing according to the control by the loaded program. The processing shown in steps S821 to S825 is processing performed by the CPU 201 of the print management server 101. A program for causing the CPU 201 of the print management server 101 to execute this processing is stored in the external memory 211 of the print management server 101. When the processing is executed, the CPU 201 loads the program into the RAM 202 and executes the processing according to control by the loaded program.

  The CPU 301 of the multi-function peripheral 103 accepts selection of a print job to be printed out via the print job selection unit 1303 on the print job list display screen 1300 shown in FIGS. 13 and 14 (step S801). When a print start instruction input by receiving a press instruction for the print button 1305 is received in a state where any print job is selected (YES in step S802), the selected print job is specified. (Step S803), and a print job output request including the acquired information is transmitted to the print management server 101 (step S804).

  As the information for specifying the print job, any information may be used as long as the information can uniquely specify the print job to be printed out, such as the job ID 1201 and the time stamp 1205.

  When the print management server 101 receives a print job output request from the multi-function peripheral 103, the print management server 101 acquires all the information specifying the print job included in the print job output request, and records a record for managing the print job specified by the information. get. Then, according to the information registered in the file name 1203 of the record, the print job that has received the print instruction (there is an output request) is acquired from the folder in which the print job is stored (step S822).

  Then, among the print jobs acquired in step S822, a print job that has not been transmitted to the MFP 103 is acquired (step S824), and the print job is transmitted to the MFP 103 that has issued the print job output request (step S825). ).

  When the CPU 301 of the multifunction machine 103 receives a print job from the print management server 101 (step S805), the CPU 301 executes a print process according to the print job (step S806).

  The CPU 201 of the print management server 101 determines whether there is a print job that has not been transmitted to the MFP 103 yet in the print job acquired in Step S823 after transmitting the print job to the MFP 103 in Step S825 (Step S825). S826).

  If “YES” is determined in the determination process of step S826, the process proceeds to step S824, an untransmitted print job is acquired, and is transmitted to the multi-function peripheral 103. This process is repeated until NO is determined in the determination process of step S826.

  Each time the CPU 301 of the multi-function peripheral 103 receives a print job transmitted from the print job from the print management server 101 (step S805), the CPU 301 executes a print process according to the print job. The above is the description of the printing process.

  According to the present invention, by configuring as described above, it is possible to limit MFPs that can print out the print data according to the security level of the print data.

  By making the above possible, when the IC card is lost or the like, there is an effect of suitably preventing a third party from outputting a highly confidential print job.

  Also, even if you forget to collect the print result after printing a highly confidential print job, there are limited multifunction devices that can output the print job. It is possible to easily identify the multifunction peripheral in which the paper is left unattended, and it is possible to quickly collect.
