Description

  The present invention is a technique for outputting print data created by an information processing apparatus from an image forming apparatus, and in particular, print data is temporarily stored in a storage device of the image forming apparatus and printed via an operation unit of the image forming apparatus. The present invention relates to a technique for outputting print data stored in a storage device when an instruction is given.

  2. Description of the Related Art Conventionally, print data created by an information processing apparatus is output from an image forming apparatus such as a printer to create distribution materials. In general, a printer is often shared by a plurality of users, and a printed matter created by a plurality of users and subjected to a print command is left in the paper discharge unit until the user comes to pick it up. Some printed matter created by a user issuing a print command has extremely high confidentiality. In that case, the user had to go to the printer immediately after issuing a print command and collect the printed material so that others could not see it. Therefore, there is a risk that the contents of confidential documents will be leaked due to forgetting to remove them. In order to deal with such problems, the print data for which the print command has been issued is temporarily stored in the print data storage area such as the hard disk of the printer, and the user who has issued the print command can print from the operation unit such as the touch panel of the printer. Printing is performed by designating data and issuing a print command. In a multifunction peripheral having a scanner function and a facsimile function in addition to a printer function, fax data and image data of a document read by a scanner can be stored in a storage area in addition to print data.

  In such a system, a logical storage area called a box is set in the storage area of the printer, and it is necessary to assign the box to a department or individual and access the data stored in the box. Set a valid password. When you save print data in a box, a password is often not required. However, when printing, specify the box where the data was saved and enter the password to select the saved print data. The screen needs to be displayed. On the selection screen, data to be actually printed is selected to give a print instruction.

  By doing so, the print data stored in the storage device is not output to a third party without permission, and it is necessary to go to the printer and give a print instruction. There is less risk of information leaking if you forget it.

  In addition, when such a function is used, a print command is mistakenly performed on the computer, and even after print data is transmitted to the printer, the print command can be canceled. It is also possible to suppress unnecessary printing due to.

In such a system, if the password is forgotten, there is a problem that the printed matter cannot be printed. Therefore, by setting a password that is valid for multiple boxes and having the administrator know it, even if there is a user who has forgotten the password, the password can be entered. Thus, the box can be accessed, so that printing can be performed (Patent Document 1).
JP 2004-104411 A

  The invention described in Patent Document 1 is effective when the user forgets the password of the box set for use by the user.

  However, when printing is performed using a password that is valid for the plurality of boxes, the print data of the boxes of other users can also be printed. Therefore, such a method has a problem that the confidentiality of the print data stored in the box cannot be maintained.

Further, when considering the security of print data stored in the storage device of the image forming apparatus, it is necessary to deal with data stored after the user logs in. As such print data, for example, there is print data transmitted from the information processing apparatus to the image forming apparatus after leaving the image forming apparatus while the user is logged in to the image forming apparatus. If print data saved after leaving the image forming apparatus can be printed, for example, by updating the print data list, not only the print data that could be specified for printing before the update but also newly saved. It becomes possible for another user to perform print processing of the print data. In consideration of the case where the newly stored print data is highly confidential, it is necessary to control such print data to be prohibited from print processing and to ensure a certain level of security for the print data.

In view of the above-described problems, the present invention prevents print data stored in a storage device of an image forming apparatus from being output after the user has logged in to the image forming apparatus. The objective is to ensure a certain level of security for printing .

  First, when the power is turned on and the image forming apparatus 101 is activated, the CPU 201 activates a box printing application, and executes box setting processing in step S401. Details of the box setting process will be described later with reference to FIG.

  Next, in step S402, the CPU 201 executes cache information creation processing. In this cache information creation process, the CPU 201 creates bibliographic data of print data stored in the HDD 204 of the image forming apparatus 101 to create cache information (FIG. 11 described later). Details of the cache information creation process will be described later with reference to FIG.

  When the cache information creation process in step S402 ends, in a step (not shown), the CPU 201 controls to display the login screen shown in FIG. 5 on the display unit of the operation unit 208.

  FIG. 5 is a schematic diagram illustrating an example of a login screen displayed on the display unit of the operation unit 208 of the image forming apparatus 101 illustrated in FIG.

  Next, the CPU 201 has received a box setting change request (setting change instruction received: S403), or has received print data having a print request using the box printing function (print data storage request: S405). ), A user login request has been received (S407), or if the user is logged in, has received a print request for saved data from the user (step S410), or has received a user logout request (step S414) Etc. are constantly monitored. This will be described in detail below.

  First, in step S403, the CPU 201 determines whether a setting change instruction has been received from the management server 103. If it is determined that a setting change instruction has been received, the process proceeds to step S404. In step S404, the CPU 201 executes a box setting change process, and proceeds to step S405. Details of the box setting change processing will be described later with reference to FIG.

  On the other hand, if it is determined in step S403 that the CPU 201 has not received a setting change instruction from the management server 103, the process proceeds directly to step S405.

  In step S405, the CPU 201 determines whether or not print data having a print request using the box print function has been received from the information processing apparatus 102. If it is determined that the print data has been received, the process proceeds to step S406. Proceed. In step S406, the CPU 201 executes a data saving process, and proceeds to step S405. Details of the data storage process will be described later with reference to FIG.

  On the other hand, if it is determined in step S405 that the CPU 201 has not received from the information processing apparatus 102 print data that has a print request using the box print function, the process proceeds directly to step S407.

  In step S <b> 407, the CPU 201 determines whether a user login request has been received from the operation unit 208.

  In the state where the login screen shown in FIG. 5 is displayed, the user holds his / her IC card over the card reader 210, and the card reader 210 acquires information stored in the IC card and inputs it to the CPU 201. Thus, a login request can be made. In order to deal with the case where the IC card is lost, for example, by touching the “keyboard input” button 2601 in FIG. 5, a user ID / password input screen (not shown) is displayed on the operation unit 208. Of course, it is also possible to make a login request based on information (user name, password, etc.) entered on the screen.

  If it is determined in step S407 that the CPU 201 has received a user login request from the operation unit 208, in step S408, the CPU 201 executes a user login process. In the login process, user authentication is performed based on information (user name, password) in the IC card read by the card reader 210 at the time of the login request, and when the user authentication is successful, the user is set in the login state. . Then, after the login process is completed, the process proceeds to step S409.

  If the user login process in step S408 is successful (user authentication is successful), the CPU 201 controls to display the initial screen shown in FIG.

  FIG. 6 is a schematic diagram illustrating an example of an initial screen displayed on the display unit of the operation unit 208 of the image forming apparatus 101 illustrated in FIG.

  On the other hand, if it is determined in step S407 that the CPU 201 has not received a user login request from the operation unit 208, the process directly proceeds to step S409.

  Next, in step S409, the CPU 201 determines whether or not the user is logged in. If the CPU 201 determines that the user is not logged in, the CPU 201 advances the process to step S416.

  On the other hand, if the CPU 201 determines in step S409 that the user is logged in, the CPU 201 advances the process to step S410.

  In step S410, the CPU 201 determines whether to print the document stored in the box.

  The user can request the image forming apparatus 101 to print the document stored in the box by touching the box print tab 2901 on the initial screen shown in FIG.

  If it is determined in step S410 that the CPU 201 prints the document stored in the box, the process proceeds to step S411. In this flowchart, after logging in, the initial screen shown in FIG. 6 is displayed, and when there is an instruction to print the document stored in the box from the initial screen, the process proceeds to step S411. ing. However, when the user logs in, if the print data corresponding to the user exists in the box used (setting instruction in 1303 and 1304 in FIG. 13 to be described later), automatically (without an instruction from the user) You may comprise so that the printing of the document preserve | saved at this box may be requested | required (that is, you may comprise so that a process may be advanced to step S411 as it is after login).

  Next, in step S411, the CPU 201 determines whether or not the direct print mode is set. The setting of the direct printing mode (setting instruction in 1301 in FIG. 13 described later) is performed by the box setting changing process in step S404 and stored in the HDD 204.

  If the CPU 201 determines in step S411 that the direct print mode has not been set, the process proceeds to step S412 to execute the print process (with UI), and the process proceeds to step S414 after completion. Details of the printing process (with UI) will be described later with reference to FIG.

  On the other hand, if the CPU 201 determines in step S411 that the direct print mode is set, the process proceeds to step S413, print processing (no UI) is performed, and the process proceeds to step S414 after the end. Details of the printing process (without UI) will be described later with reference to FIG.

  On the other hand, if the CPU 201 determines in step S410 not to print the document stored in the box, the CPU 201 advances the process to step S414 as it is.

  Next, in step S414, the CPU 201 determines whether or not there is a logout request. The user can make a logout request to the image forming apparatus 101 by pressing an ID key (not shown) of the operation unit 208.

  If the CPU 201 determines in step S414 that there has been a logout request, in step S415, the CPU 201 executes user logout processing, and proceeds to step S416 after completion. Further, even when an operation instruction from the user via the operation unit 208 is not input for a certain period of time, the CPU 201 considers that a logout request has been made.

  On the other hand, if the CPU 201 determines in step S414 that there is no logout request, the process proceeds directly to step S416.

  Next, in step S416, the CPU 201 determines whether or not it is an end due to a power shutdown or the like. If it is determined that the end is not an end, the process returns to step S403.

  On the other hand, if the CPU 201 determines in step S416 that the processing has ended, the processing ends.

  The box setting process shown in step S401 of FIG. 4 will be described below with reference to FIG.

  FIG. 7 is a flowchart illustrating an example of a second control processing procedure according to the present invention, which is realized by the CPU 201 of the image forming apparatus 101 reading and executing a program stored in the ROM 203 or the HDD 204.

  Note that the processing in this flowchart corresponds to the box setting processing shown in step S401 in FIG. This process is performed based on the control of the box printing application program that is activated when the power of the image forming apparatus 101 is turned on. In the figure, S501 to S509 indicate each step.

First, in step S <b> 501, the CPU 201 searches the HDD 204 for an old setting file in which setting information before setting change is recorded. Here, the old setting file will be described. The old setting file is generated when a change is made to the box setting (that is, in step S404 in FIG. 4), and the previous setting is initialized in order to change the box setting after rebooting. Data necessary for this is recorded. Specifically, it is box information to be processed in which print data used by the application program is stored, password information necessary for accessing the box, and the like. The old setting file is saved with a preset file name, and the CPU 201 searches whether a file having the file name exists in a predetermined area (logical) of the HDD 204.

  If the CPU 201 determines in step S501 that there is an old setting file, the process proceeds to step S502. In step S502, the CPU 201 accesses the box according to the box setting before change recorded in the old setting file, and cancels the password set for all the boxes to be processed by the application program. Cancel the settings of and initialize the settings for the box. Then, the process proceeds to step S503.

  On the other hand, if the CPU 201 determines in step S501 that there is no old setting file, the process proceeds directly to step S503.

  Next, in step S503, the CPU 201 determines whether or not the HDD 204 has a setting file necessary for setting the box. If it is determined that there is no setting file, the process proceeds to step S504. In step 504, the CPU 201 creates a new setting file (with default settings stored in the HDD 204) based on the control of the application program. Then, the process proceeds to step S505.

  On the other hand, if the CPU 201 determines in step S503 that the setting file necessary for setting the box exists in the HDD 204, the process proceeds directly to step S505.

  Next, in step S505, the CPU 201 performs setting for the box to be processed based on the setting file, and proceeds to step S506.

  Next, in step S506, the CPU 201 determines whether the setting process for the box has ended normally. If it is determined that the setting process has ended normally, the CPU 201 advances the process to step S507.

  In step S507, the CPU 201 determines whether or not the old setting file is stored in the HDD 204. If the CPU 201 determines that the old setting file is stored in the HDD 204, the process proceeds to step S508. In step S508, the CPU 201 deletes the old setting file and ends the process.

  On the other hand, if the CPU 201 determines in step S507 that the old setting file is not stored in the HDD 204, the processing ends.

  If the CPU 201 determines in step S506 that the setting process for the box has not ended normally, the process proceeds to step S509. In step S509, the CPU 201 performs error notification processing. For example, the CPU 201 controls the display of the message screen as shown in FIG. 8 on the display unit of the operation unit 208, and further notifies the error to the email address of an administrator or the like registered in advance in the HDD by means such as email. I do. Then, after the error notification in step S509, the process ends. The above is the box setting process performed when the image forming apparatus is activated.

  In step S506, setting (password setting) for some of the boxes designated as application processing targets has not been performed normally (access using a password in the setting file). If the CPU 201 determines that the setting process for the box did not end normally due to the failure, the part of the boxes may be excluded from the processing targets of the application and the processing described below may be performed. Of course it is good. At that time, if the part of the boxes are set as “monitoring target boxes”, the sorting process is not performed. In addition, when “Used box” is specified, if “Distribute documents to be saved” is set, data is not sorted into the box, but is stored in the box. The bibliographic information of the print data is not created. The distribution process and bibliographic information creation process will be described later.

  FIG. 8 is a schematic diagram illustrating an example of a message screen displayed on the display unit of the operation unit 208 when the setting process for the box does not end normally.

  Hereinafter, with reference to FIG. 9, the cache information creation processing shown in step S402 of FIG. 4 will be described.

  FIG. 9 is a flowchart illustrating an example of a third control processing procedure according to the present invention, which is realized by the CPU 201 of the image forming apparatus 101 reading and executing a program stored in the ROM 203 or the HDD 204. Note that the processing in this flowchart corresponds to the cache information creation processing shown in step S <b> 402 of FIG. 4, and cache information that is bibliographic information of print data received from the information processing apparatus 102 and stored in the HDD 204. It is a process for creating. In the figure, S601 to S613 indicate each step.

  First, in step S601, the CPU 201 reads a setting file stored in the HDD 204, and the range of the box to be processed by the box printing application program (the range of the box to be used; setting instruction in 1304 in FIG. 13 described later). To get.

  In step S602, the CPU 201 acquires a list of pointers (data for specifying boxes) for accessing the box used by the box printing application program acquired in step S601.

  In step S603, the CPU 201 determines whether or not the pointer list has been successfully acquired. If it is determined that the pointer list has not been acquired, the CPU 201 proceeds to step S613 to perform error notification processing. For example, the CPU 201 controls the display of a message screen on the display unit of the operation unit 208, and further notifies the error to the mail address of an administrator or the like registered in advance in the HDD by means such as mail. And a process is complete | finished after the error notification of step S613. Note that when the process ends in an error, the box printing application ends without performing a series of processes after step S403 in FIG.

  On the other hand, if the CPU 201 determines in step S603 that the pointer list has been successfully acquired, the process proceeds to step S604.

  Next, in steps S604 to S611, the CPU 201 performs processing for obtaining all print data stored in all boxes used by the application. Details will be described below.

  First, in step S604, the CPU 201 determines whether or not the processing in steps S605 to S611 has been completed for all boxes used by the application. If it is determined that the processing has not yet been completed, the process proceeds to step S605. To proceed.

  In step S605, the CPU 201 sets an ID of a box for acquiring a print document. Next, in step S606, the CPU 201 accesses the box using the pointer information for accessing the box having the ID in the pointer list acquired in step S602, and stores all the information stored in the box. Get in-box data information. Note that the print data stored in each box is managed by the in-box data information as shown in FIG. 10 for each box. Here, the in-box data information will be described with reference to FIG.

  FIG. 10 is a data configuration diagram showing an example of in-box data information set for each box of the image forming apparatus 101 shown in FIG.

  As shown in FIG. 10, the in-box data information includes a document ID 2701, path information 2702, and user information 2703. The document ID 2701 is unique data added for each document by the image forming apparatus 101. The path information 2702 stores path information in the HDD 204 in which data is actually stored. User information 2703 stores user information such as a user name. The user information 2703 may be configured not to be included in the box data information but to be included in actual data.

  Using the in-box data information shown above, the CPU 201 can acquire all the print data stored in the box in the range to be used. It is possible to register other than print data such as facsimile data or image data read and created by a scanner in the box, but it is assumed that such data is not acquired in step S606. For example, the print data is specified based on the data structure (header information or the like) and only the print data is acquired.

  Next, in step S607, the CPU 201 determines whether or not the print data has been successfully acquired in step S606. Note that the administrator can change the password of each box after the application is started by means different from the box printing application. For example, if a password that is different from the password set for the box in the setting information file is set for the box that is to be processed by this box printing application, an authentication error occurs and the information can be acquired. It may disappear. In such a case, acquisition of print data fails.

  If the CPU 201 determines in step S607 that acquisition of print data has failed in step S606, the process proceeds to step S613, an error is notified, and the process ends.

  In this embodiment, when an error occurs in the access process for the box to be processed, the process is terminated, but the box that has failed to access is regarded as a target for creating cache information. Of course, it is possible to continue the processing by excluding the box.

  On the other hand, if the CPU 201 determines in step S607 that the print data has been successfully acquired in step S606, the process proceeds to step S608.

  Next, in steps S608 to S611, the CPU 201 executes processing for acquiring bibliographic information from all the print data acquired in step S606 and adding it to the cache information. Details will be described below.

  In step S608, the CPU 201 determines whether or not the processing from steps S609 to S611 has been completed for all the print data acquired in step S606. If it is determined that the processing has not yet been completed, the processing proceeds to step S609. To proceed.

  In step S609, the CPU 201 sets a document ID to specify print data, and in step S610, acquires bibliographic information included in the print data specified by the document ID. Here, the bibliographic information is specifically the name of the user who issued the print instruction, the name of the file, the name of the application (APP name) in which the print data was created, the number of pages, the number of copies, and the time stamp indicating the date and time of reception. .

  In step S611, the CPU 201 shows the bibliographic information information acquired in step S610 as cache information together with the document ID for uniquely identifying the print data and the ID information of the box in which the print data is stored, as shown in FIG. It is additionally stored in the RAM 202. The cache information storage destination may be the HDD 204. Here, the cache information will be described with reference to FIG.

  FIG. 11 is a data configuration diagram illustrating an example of cache information acquired from print data stored in the image forming apparatus 101 illustrated in FIG. 1.

  As shown in FIG. 11, the cache information includes a document ID, a user name, a file name, an APP name, a storage box, the number of pages, the number of copies, a time stamp, and the like. Using the cache information shown above, the CPU 201 can generate a print data list to be described later.

  Hereinafter, the description returns to the flowchart of FIG.

  When the process of step S611 is completed, the CPU 201 returns the process to step S608.

  If the CPU 201 determines in step S608 that the processing from steps S609 to S611 has been completed for all the print data acquired in step S606, the process returns to step S604.

  If the CPU 201 determines in step S604 that the processes in steps S605 to S611 have been completed for all boxes used by the application, the process proceeds to step S612.

  Next, in step S612, the CPU 201 sorts the bibliographic information included in the cache information stored in the RAM 202 in the order of high printing priority (for example, the received order), and ends this processing. To do. The above is the cache information creation process performed when the image forming apparatus is activated.

  In this embodiment, if the data stored in the box cannot be accessed (NO in step S607), the process is terminated. However, only the print data stored in the box is not acquired. Of course, a method of acquiring print data stored in the next box may be adopted.

  In the present invention, a conventional method for designating a box assigned to each user (group) and displaying the data stored in the box so as to be selectable is different, and is set in advance in the image forming apparatus. Print data (excluding FAX data and image data created by the scanner unit) saved by the logged-in user among the data saved in the box (a plurality of cases) can be displayed in a selectable manner.

  In the present invention, by adopting the configuration as described above, it is possible to more efficiently perform print data selection screen information for the user after user login.

  Further, in the conventional method, there is a risk that information may be leaked because the document is printed without permission when the user mistakenly stores it in a box assigned to another user due to an operation error of the user. Since only the user who saved the print data can issue a print instruction for the data, the risk of information leakage due to a user operation error is reduced.

  Hereinafter, with reference to FIG. 12, the box setting changing process shown in step S404 of FIG. 4 will be described.

  FIG. 12 is a flowchart showing an example of a fourth control processing procedure in the present invention. Note that the processing in steps S721 to S728 in this flowchart corresponds to the box setting change processing shown in step S404 in FIG. 4, and the CPU 201 of the image forming apparatus 101 reads out the program stored in the ROM 203 or the HDD 204. It is realized by executing. S701 to S707 correspond to processing on the management server 103 side, and are realized by the CPU 301 of the management server 103 reading and executing a program stored in the HDD.

  First, in step S <b> 701, when there is a box setting change request in response to an instruction from the input unit of the administrator who operates the management server 103, the CPU 301 of the management server 103 issues a box setting screen request to the image forming apparatus. 101 is transmitted.

  Upon receiving a request from the management server 103 (S721), the CPU 201 of the image forming apparatus 101 transmits box setting screen information shown in FIG. 13 to the management server 103 in step S722.

  When the CPU 301 of the management server 103 receives the screen information (FIG. 13) from the image forming apparatus 101 (S702), the CPU 301 displays the received screen information on the display device 311 of the management server 103 in step S703. Here, the box setting screen will be described with reference to FIG.

  FIG. 13 is a schematic diagram illustrating an example of a box setting screen transmitted from the image forming apparatus 101 to the management server 103 when the box setting is changed.

  In FIG. 13, reference numeral 1301 denotes a “stored document list display” setting, which is set to perform direct printing (print mode without UI) or not (print mode with UI).

  Reference numeral 1302 denotes a “stored document distribution” setting, which can be set to whether or not to distribute print data stored in the monitoring target box. When “No” is set, control is performed so that the “monitoring target box” setting 1303 is not performed (even if it is performed, it is invalid).

  The “monitor target box” setting 1303 is moved to one of the boxes set in the “used box” setting 1304 when the print data is stored in this box.

  The “box to use” setting 1304 is the target of processing of the box print application program for the print data stored in the box set here (excluding FAX data and image data created by reading with a scanner) ).

  1305 is a “box password” setting, 1306 is a “password confirmation input”, and a password for accessing the box set in the “used box” setting 1304 can be set. Note that the password set here is applied to all boxes set in the “monitoring target box” setting 1303 and the “used box” setting 1304.

  Reference numeral 1307 denotes an “automatic erasure of a document after printing” setting, which can be set to erase or not erase data from the HDD after print processing.

  Reference numeral 1308 denotes a “set” button. When this button is instructed by the keyboard 308 or the pointing device 307, the CPU 301 of the management server 103 transmits the information set on this screen to the image forming apparatus 101. Control.

Information, box range information to be used, and box password information) are stored in the HDD 204 as an old setting file. At this time, if the data to be saved in the old setting file (monitoring destination box information, used box range information, box password information) has not been changed, the old setting file is not created. May be.

  In step S725, the CPU 201 of the image forming apparatus 101 replaces the contents of the setting file with the setting information received from the management server 103 in step S723.

  Next, in step S <b> 726, the CPU 201 of the image forming apparatus 101 generates setting end notification screen information as illustrated in FIG. 14 based on the setting file replaced in step S <b> 725 and transmits it to the management server 103.

  Upon receiving the setting end notification screen information (FIG. 14) from the image forming apparatus 101, the CPU 301 of the management server 103 controls the display of the received setting end notification screen information on the display device 311 of the management server 103 (S707). The process ends.

  FIG. 14 is a schematic diagram illustrating an example of setting end notification screen information transmitted from the image forming apparatus 101 to the management server 103 when the box setting change ends.

  As illustrated in FIG. 14, in the setting end notification screen information, as illustrated in 1401, an instruction to prompt the image forming apparatus 101 to restart is issued. When the image forming apparatus 101 is restarted, the setting is changed as indicated by reference numeral 1402.

  Thereafter, when the CPU 201 of the image forming apparatus 101 receives a restart instruction for restart (S727), in step S728, the CPU 201 executes the restart process and ends the process.

  In the image forming apparatus 101, when the restart is performed, the setting process shown in step S401 (FIG. 5) in FIG. 4 is performed, and the setting change is completed. The above is an example of the box setting change process.

  In FIG. 22, reference numeral 2301 denotes a “canceled” button for instructing print cancellation. When the “Cancel” button 2301 is touched, a print job in which a printing error has occurred due to no paper is skipped (printing is canceled).

  Reference numeral 2302 denotes an “erase document after cancel” button for instructing to cancel printing and to delete print data. When the “delete document after cancel” button 2302 is touched, a print job that causes a print error due to no paper is skipped (printing is canceled) and the print data is deleted from the HDD 204 of the image forming apparatus 101. .

  When a “Cancel” button 2301 is touched, a print job that causes a printing error due to no paper is skipped (printing is canceled).

  Hereinafter, the description returns to the flowchart of FIG.

  Next, in steps S1007 to S1009, the CPU 201 of the image forming apparatus 101 is instructed to cancel printing within a preset time (predetermined time) (S1008), or has the corresponding paper been replenished within the predetermined time? (S1009) is determined.

  If it is determined that the corresponding sheet has been replenished within the predetermined time (YES in S1009), the CPU 201 of the image forming apparatus 101 advances the process to step S1010. In step S1010, the CPU 201 of the image forming apparatus 101 hides the error display (FIG. 22) displayed on the operation unit 208, returns the screen to FIG. 21, and notifies the user that the error state has been recovered. At the same time, the process advances to step S1011 to perform print processing of the print data.

  If cancellation of printing is instructed within a predetermined time (specifically, “Cancel” button 2301 or “Delete document after cancellation” button 2302 in FIG. 22 is instructed) (YES in S1008), Alternatively, if the predetermined time has elapsed without recovery from the error state and the cancel instruction (YES in S1007), the CPU 201 of the image forming apparatus 101 advances the process to step S1016.

  In step S1016, the CPU 201 of the image forming apparatus 101 hides the error display (FIG. 22) for the print data, returns the screen to FIG. 21, notifies the user that the print data is to be skipped, and performs step S1017. Then, the print data is excluded from the print target data.

  Thereafter, in step S1018, the CPU 201 of the image forming apparatus 101 determines whether there is an instruction to delete the print data. In the present embodiment, if the printing is canceled due to the instruction of the “delete document after cancellation” button 2303 in FIG. 22, it is determined that a deletion instruction has been issued.

  If it is determined in step S1018 that there is a deletion instruction, in step S1019, the CPU 201 of the image forming apparatus 101 deletes the print data from the HDD 204. In step S1020, the bibliographic information of the print data is also obtained from the cache information. Is deleted. Here, the user may be notified that the print data has been deleted. Then, the CPU 201 of the image forming apparatus 101 returns the process to step S1003, and proceeds to a print process for the next print data.

  On the other hand, if it is determined in step S1018 that there is no deletion instruction, the CPU 201 of the image forming apparatus 101 returns the process to step S1003 as it is, and proceeds to a printing process for the next print data.

  Further, after the printing process in step S1011 is completed, the CPU 201 of the image forming apparatus 101 changes the status of the print data held on the RAM 202 to “printed” in step S1012.

  In step S <b> 1013, the CPU 201 of the image forming apparatus 101 determines whether there is a deletion setting for printed data. Specifically, if the box setting process of S404 (FIG. 4) has been performed with the “automatic erasure of printed document” setting 1307 in FIG. 13 and the setting of S404 (FIG. 4) being performed, the CPU 201 of the image forming apparatus 101 It is determined that the printed data is to be erased.

  If it is determined in step S1013 that there is a setting for deleting data that has been printed, the CPU 201 of the image forming apparatus 101 deletes the print data that has been printed from the HDD 204 in step S1014. Thereafter, in step S1015, the CPU 201 of the image forming apparatus 101 deletes the bibliographic information (including the document ID) of the print data from the cache information, returns the process to step S3, and proceeds to the print process of the next print data. .

  On the other hand, if it is determined in step S1013 that there is no setting for deleting data that has been printed, the CPU 201 of the image forming apparatus 101 directly returns to step S1003 and proceeds to print processing for the next print data.

  The above processing is performed until the printing processing of all the print data selected in the print data list (in the print data list created in step S1002) is completed. That is, if the CPU 201 of the image forming apparatus 101 determines in step S1003 that the print processing of all the print data indicated by the print data list of the user has been completed, the CPU 201 of the image forming apparatus 101 The process ends. The above is the printing process (no UI).

  With this configuration, in order to print data stored in a box in the past, a storage destination box is specified, and data to be actually printed is specified and printed. Although this is troublesome for the user, it is possible to save the trouble and improve the processing efficiency.

  In a configuration in which print data is stored in a box and then printed, there may be a time interval between print data creation and print processing by the image forming apparatus. It is conceivable that there is a sheet when the printing instruction is given, but the sheet is cut out when printing is actually performed, or the setting of the sheet cassette in the sheet feeding stage is changed. If the paper is simply cut, the printing can be skipped to enable smooth printing. Then, the printing process can be performed again by replenishing the paper. In addition, when the setting of the paper cassette in the paper feed stage has been changed, it is possible that the printing process will fail until the paper is set again in the paper cassette. In that case, it is possible not only to skip but also to delete the print data.

  Hereinafter, the printing process (with UI) shown in step S412 of FIG. 4 will be described with reference to FIGS. 23A and 23B.

  23A and 23B are flowcharts showing an example of the eighth control processing procedure in the present invention, and correspond to the printing processing (with UI) shown in step S412 of FIG. This process is performed when the “stored document list display” setting value 1302 is set to “Yes” in the box setting screen shown in FIG. The processing of this flowchart is realized by the CPU 201 of the image forming apparatus 101 reading and executing a program stored in the ROM 203 or the HDD 204. S1101 to S1127 indicate each step.

  First, in step S1101, the CPU 201 of the image forming apparatus 101 creates a print data list stored in the HDD 204 of the image forming apparatus 101 by the currently logged-in user (hereinafter referred to as the user). Process. Details will be described later with reference to FIG.

  Next, in step S <b> 1102, the CPU 201 of the image forming apparatus 101 displays a print data list as illustrated in FIG. 24 on the display unit of the operation unit 208 of the image forming apparatus 101. Here, the print data list screen will be described with reference to FIG.

  FIG. 24 is a schematic diagram illustrating an example of a print data list screen displayed on the display unit of the operation unit 208 of the image forming apparatus 101 during print processing (with UI).

  On this print data list screen, only a predetermined number or less of the print data registered by the user is displayed. That is, not all print data in the print list data created in step S1101 is displayed on this print data list screen (it cannot be designated as a print target).

  This configuration is for preventing a single user from occupying the image forming apparatus 101 for a long time in order to perform print processing because the image forming apparatus 101 is shared by a plurality of users (at a time). The number of print data that can be printed is limited.)

  In FIG. 24, reference numeral 1501 denotes a logged-in user display field, which displays logged-in user information (here, “user A” is logged in).

  A list box 1502 displays print data saved by the logged-in user, and the user selects a document to be printed (or a document to be deleted) from the list box 1502. A plurality of list boxes 1502 can be selected. If the list box 1502 cannot be displayed, the pages can be changed (scrolled) using the “▲” and “▼” buttons. Reference numeral 1503 denotes a document number display field that displays the number of data to be selected.

1504 is the "update" button, is used to perform the update processing of the data that is displayed in the list box 1502 and then re-create the print data list. By repeatedly using this "update" button 150 4, the print processing of all the print data corresponding to the user, it is possible to perform the removal process or the like.

  Reference numeral 1505 denotes a print number display column, which displays the number of copies to be printed. Note that this print copy number display column can be changed with a numeric keypad (not shown) of the operation unit 208. Further, when the number of print copies is changed, it is applied to all print data selected in the list box 1502.

  Reference numeral 1506 denotes a “delete document after printing” check box. When printing of a document selected in the list box 1502 is finished, it is possible to set whether to delete data from the HDD 204 (checked) or not (not checked). is there. Note that the default follows the box setting and can be changed.

  Reference numeral 1507 denotes an “select all” button, which is used to select all print data displayed in the list box 1502. Reference numeral 1508 denotes a “selection release” button, which is used to cancel all selection states of the list box 1502.

  Reference numeral 1509 denotes an “erase” button, which is used when the print data selected in the list box 1502 is erased. When this button is touched, a confirmation screen 1600 shown in FIG. 25 is displayed.

  FIG. 25 is a schematic diagram showing an example of a confirmation screen displayed when the “delete” button 1509 shown in FIG. 24 is designated.

  In FIG. 25, reference numeral 1601 denotes a “Yes” button. When this button is touched, an instruction to delete the print data selected in the list box 1502 is issued, and the confirmation screen 1600 is closed.

  Reference numeral 1602 denotes a “No” button. When this button is touched, a delete instruction is not issued and the confirmation screen 1600 is closed.

  Returning to the description of FIG.

  In FIG. 24, reference numeral 1510 denotes a “print button”, which is used when instructing execution of printing of print data selected in the list box 1502. When this button is touched, a confirmation screen 1700 shown in FIG. 26 is displayed.

  FIG. 26 is a schematic diagram illustrating an example of a confirmation screen displayed when the “print” button 1510 illustrated in FIG. 24 is designated.

  In FIG. 26, reference numeral 1701 denotes a “Yes” button. When this button is touched, a print instruction for print data selected in the list box 1502 is issued, and the confirmation screen 1700 is closed.

  Reference numeral 1702 denotes a “No” button. When this button is touched, a print instruction is not issued and the confirmation screen 1700 is closed.

  Returning to the description of FIG.

  In FIG. 24, a button 1511 is used when instructing the end of the printing process (with UI). When the button 1511 is touched, the CPU 201 of the image forming apparatus 101 controls to close the print data list screen of FIG. 24 and display the initial screen shown in FIG.

  Although not shown in FIG. 24, a “print setting change” button is provided on the print data list screen, and print settings of the print data selected in the list box 1502 (for example, the number of copies, stapling processing, bookbinding processing) The post-processing, etc., and the setting of both sides / one side, etc.) may be changeable.

  Returning to the flowchart of FIG.

  After the print data list display (FIG. 24) is performed in step S1102, in step S1103, the CPU 201 of the image forming apparatus 101 performs display update issued when the user touches the “update” button 1504 in FIG. It is determined whether there is an instruction.

  If it is determined in step S1103 that a display update instruction has been received, the CPU 201 of the image forming apparatus 101 returns the process to step S1101, and executes the print data list creation process for the user again.

  On the other hand, if it is determined in step S1103 that the display update instruction has not been received, the CPU 201 of the image forming apparatus 101 receives a print data selection instruction in the list box 1502 in FIG. It is determined whether or not the input has been made.

  If it is determined in step S1104 that a print data selection instruction has been input via the operation unit 208, in step S1105, the CPU 201 of the image forming apparatus 101 selects the designated print data. To control. If the print data designated in the list box 1502 is already selected, the selected state is cancelled. Then, the process proceeds to step S1106.

  In step S <b> 1006, the CPU 201 of the image forming apparatus 101 determines whether a print data deletion instruction has been input via the operation unit 208.

  If it is determined in step S1006 that a print data deletion instruction has been input, the CPU 201 of the image forming apparatus 101 deletes the bibliographic information indicating the selected print data from the cache information in step S1109. In step S1110, the print data indicated by the bibliographic information is deleted from the HDD 204. Then, the process returns to step S1101. Even if it is determined that the instruction of the “erase” button 1509 has been received, if there is no selected print data, the processing is continued assuming that no deletion instruction has been received.

  On the other hand, if it is determined in step S1106 that no deletion instruction has been received, the CPU 201 of the image forming apparatus 101 proceeds to step S1107 and determines whether a printing instruction has been received.

  If it is determined in step S1107 that a print instruction has not been received, the CPU 201 of the image forming apparatus 101 returns the process to step S1103.

  On the other hand, if it is determined in step S1107 that a print instruction has been received, the CPU 201 of the image forming apparatus 101 proceeds to step S1108 until it is determined that printing of all print data to be printed has been completed (in step S1108). YES), control is performed so as to perform the processing of steps S1112 to S1127 shown in FIG. 23B. Hereinafter, the details of the processing of steps S1112 to S1127 will be described with reference to FIG. 23B.

  First, in step S <b> 1112 of FIG. 23B, the CPU 201 of the image forming apparatus 101 acquires print data with the highest priority from the print target data from the HDD 204. Hereinafter, this print data is referred to as the print data. At this time, the status of the print data is held in the RAM 202 as “unprinted”.

  In step S <b> 1113, the CPU 201 of the image forming apparatus 101 acquires paper information to be printed from the print data, and whether the paper corresponding to the paper information is in the paper cassette of the paper feed stage of the image forming apparatus 101. Determine whether or not. If it is determined that the paper corresponding to the paper information is in the paper cassette of the paper feed stage of the image forming apparatus 101, the process proceeds to step S1118, and the print data is printed. At this time, the CPU 201 of the image forming apparatus 101 controls to display a screen 1800 as shown in FIG. 27 on the display unit of the operation unit 208.

  FIG. 27 is a schematic diagram illustrating an example of a screen displayed on the display unit of the operation unit 208 of the image forming apparatus 101 during printing.

  In FIG. 27, reference numeral 1801 denotes a “cancel” button, which is used when printing processing is stopped. When this button is designated, the CPU 201 of the image forming apparatus 101 controls to display a cancel screen 1900 as shown in FIG. 28 on the display unit of the operation unit 208.

  FIG. 28 is a schematic diagram illustrating an example of a screen displayed on the display unit of the operation unit 208 of the image forming apparatus 101 when printing is canceled.

  Although not shown in the flowchart of FIG. 23, when the “cancel” button 1801 is touched during printing, the CPU 201 of the image forming apparatus 101 ends the processing of the flowchart of FIG. At this time, when “delete document after printing” is set, the CPU 201 of the image forming apparatus 101 executes processes such as deleting only the print data that has been printed and deleting all.

  Hereinafter, the description returns to the flowchart of FIG. 23B.

  On the other hand, if the CPU 201 of the image forming apparatus 101 determines in step S1113 that there is no sheet on which the print data is to be printed in the sheet cassette of the paper feed stage of the image forming apparatus 101, the process proceeds to step S1114.

  In step S <b> 1114, the CPU 201 of the image forming apparatus 101 temporarily stops the printing process and displays an error on the display unit of the operation unit 208. For example, a screen as shown in FIG. 22 is displayed. Then, the process proceeds to step S1115.

  Next, in steps S <b> 1115 to S <b> 1117, has the CPU 201 of the image forming apparatus 101 instructed to cancel printing within a preset time (predetermined time) (S <b> 1116) or has the corresponding paper been replenished within the predetermined time? (S1117) is determined.

  If it is determined that the corresponding sheet has been replenished within the predetermined time (YES in S1117), the CPU 201 of the image forming apparatus 101 displays an error display (FIG. 22) displayed on the operation unit 208 in a step not shown. The user is notified that the error state is not displayed and the error state is recovered, and the screen is returned to FIG. 27. In step S1118, the print data is printed.

  If the predetermined time has passed without the cancel instruction recovering from the error state (YES in S1115), the CPU 201 of the image forming apparatus 101 sets the priority of the print data to the lowest in a step not shown. The process is returned to step S1108, and the process proceeds to the next print data. However, the present invention is not limited to this, and for example, it may be handled in the same manner as when the “Cancel” button 2301 is pressed to cancel printing.

  If cancellation of printing is instructed within a predetermined time (specifically, “Cancel” button 2301 or “Delete document after cancellation” button 2302 in FIG. 22 is instructed) (YES in S1116), In a step (not shown), the error display (FIG. 22) for the print data is not displayed, the screen is returned to FIG. 27, and the process proceeds to step S1123.

  In step S1123, the CPU 201 of the image forming apparatus 101 determines whether there is an instruction to delete the print data. In the present embodiment, if the printing is canceled due to the instruction of the “delete document after cancellation” button 2303 in FIG. 22, it is determined that a deletion instruction has been issued.

  If it is determined in step S1123 that there is a deletion instruction, in step S1124, the CPU 201 of the image forming apparatus 101 excludes the print data from the print target, returns the process to step S1108, and processes the next print data. Migrate to

  On the other hand, if it is determined in step S1123 that there is no deletion instruction, in step S1125, the CPU 201 of the image forming apparatus 101 excludes the print data from the print target, and the process proceeds to step S1126.

  In step S1126, the CPU 201 of the image forming apparatus 101 deletes the print data from the HDD 204, and in step S1127, deletes the bibliographic information (including the document ID) of the print data from the cache information. Then, the process returns to step S1108, and the process proceeds to the process for the next print data.

  After the printing process in step S1118 is completed, the CPU 201 of the image forming apparatus 101 changes the status of the print data stored on the RAM 202 to “printed” in step S1119.

  In step S1120, the CPU 201 of the image forming apparatus 101 determines whether there is a deletion setting for printed data. Specifically, in the case where the box setting process in S404 (FIG. 4) has been performed with the “automatic erasure after printing” setting 1307 in FIG. 13 set to “Yes”, the CPU 201 of the image forming apparatus 101 It is determined that the printed data is to be erased.

  If it is determined in step S1120 that there is a setting for deleting data that has been printed, the CPU 201 of the image forming apparatus 101 deletes the print data that has been printed from the HDD 204 in step S1121. Thereafter, in step S1122, the CPU 201 of the image forming apparatus 101 deletes the bibliographic information (including the document ID) of the print data from the cache information, returns the process to step S3, and proceeds to the print process of the next print data. .

  On the other hand, if it is determined in step S1122 that there is no setting for deleting data that has been printed, the CPU 201 of the image forming apparatus 101 returns to step S1008 and proceeds to print processing for the next print data.

  The above processing is performed until the printing processing for all the print data selected in the print data list (in the print data list selected in step S1106) is completed.

  If the CPU 201 of the image forming apparatus 101 determines in step S1108 in FIG. 23A that printing of all print data to be printed has been completed, the CPU 2000 operates a screen 2000 as shown in FIG. The information is displayed on the display unit 208, and the process proceeds to step S1111.

  FIG. 29 is a schematic diagram illustrating an example of a screen displayed on the display unit of the operation unit 208 of the image forming apparatus 101 when printing is completed.

  In FIG. 29, reference numeral 2001 denotes an “OK” button. When this button is touched, the CPU 201 of the image forming apparatus 101 closes the screen 2000.

  Hereinafter, the description returns to the flowchart of FIG. 23A.

  Next, in step S <b> 1111, the CPU 201 of the image forming apparatus 101 determines whether to continue the printing process. Note that the CPU 201 of the image forming apparatus 101 determines that the printing process is continued when the “update” button 1504 in FIG. 24 is touched in a state where the printing process of the print data to be printed has been completed. . On the other hand, when all the printing processes of the print data to be printed have been completed, if the button 1511 in FIG. 24 is touched, it is determined that the printing process is not continued (the printing process is terminated).

  If it is determined in step S1111 that the printing process is to be continued, the CPU 201 of the image forming apparatus 101 returns the process to step S1101.

  On the other hand, if it is determined in step S1111 that the printing process is not continued, the CPU 201 of the image forming apparatus 101 ends the process of this flowchart as it is. The above is the printing process (with UI).

  Hereinafter, the print data list creation processing of the user shown in step S1002 in FIG. 20 and step S1101 in FIG. 23A will be described with reference to the flowchart in FIG. That is, print data list information (print data list) that is transmitted from the information processing apparatus 102 to the image forming apparatus 101 and stored in the HDD 204 of the image forming apparatus 101 is created based on an instruction of a logged-in user. Processing will be described.

  FIG. 30 is a flowchart showing an example of a ninth control processing procedure according to the present invention, and corresponds to the print data list creation processing of the user shown in step S1002 in FIG. 20 and step S1101 in FIG. 23A. Note that the processing of this flowchart is realized by the CPU 201 of the image forming apparatus 101 reading and executing a program stored in the ROM 203 or the HDD 204. S1201 to S1204 indicate each step.

  First, in step S <b> 1201, the CPU 201 of the image forming apparatus 101 acquires bibliographic information of the user's print data included in the cache information stored in the RAM 202 or the HDD 204 of the image forming apparatus 101.

  In step S <b> 1202, the CPU 201 of the image forming apparatus 101 rearranges the bibliographic information acquired in step S <b> 1201 in order of printing priority, and creates a print data list on the RAM 202.

  In step S1203, the CPU 201 of the image forming apparatus 101 prints the bibliographic information of the print data transmitted from the information processing apparatus 102 to the image forming apparatus 101 after the user logs in the print data list created in step S1202 ( It is determined whether or not (Document ID) is included. This determination is made by comparing the time when the login process is performed on the logged-in user and the time stamp information of the bibliographic information of all the print data included in the print data list.

  In step S1203, the CPU 201 of the image forming apparatus 101 determines that the print data list does not include the bibliographic information of the print data transmitted from the information processing apparatus 102 to the image forming apparatus 101 after the user logs in. If so, the process ends.

  On the other hand, in step S1203, the CPU 201 of the image forming apparatus 101 determines that the print data list includes the bibliographic information of the print data transmitted from the information processing apparatus 102 to the image forming apparatus 101 after the user logs in. If so, the process advances to step S1204.

  In step S1204, the CPU 201 of the image forming apparatus 101 excludes the bibliographic information of the print data received after user login from the print data list and stored in the HDD 204, and the process ends. The above is the print data list creation process.

  With this print data list creation process, the print data transmitted from the information processing apparatus 102 after the user logs in is controlled not to be included in the print data list.

  Note that the print data transmitted from the information processing apparatus 102 after the user logs in can be the following (1) and (2).

  (1) While the user is operating on the image forming apparatus 101 side, a third party illegally transmitted to the image forming apparatus 101 using the information processing apparatus 102 of the user who has logged into the image forming apparatus 101 Print data.

  (2) Print data transmitted once from the information processing apparatus 102 to the image forming apparatus 101 by the logged-in user once leaving the image forming apparatus 101 while logged in to the image forming apparatus 101.

  As described above, there is a possibility that the print data transmitted from the information processing apparatus 102 after the user logs in includes illegal print data such as (1). Therefore, in the present embodiment, control is performed so as to prohibit such data printing processing, and security is ensured.

  In the case of (2), if printing of data stored after login (before logout) is enabled, for example, the user forgets logout processing and leaves the image forming apparatus. In addition, for example, when another user instructs the “update” button 1504 in FIG. 24, not only the print data already displayed in FIG. It becomes possible to do. If the print data is highly confidential, there is a risk of information leaking. In this embodiment, by adopting such a configuration, a certain level of security is ensured even in the case of (2).

  If it is determined in step S1203 that the print data list includes the bibliographic information of the print data transmitted from the information processing apparatus 102 to the image forming apparatus 101 after the user logs in, the print data list includes the print data list. You may comprise so that a user may select whether bibliographic information is included in a print data list.

  In the print data list, whether or not the bibliographic information of the print data transmitted from the information processing apparatus 102 to the image forming apparatus 101 after the user logs in is included in the print data list is set in advance from the setting screen of FIG. You may comprise so that it may make it.

  As described above, in the image forming system of the present embodiment, the image forming apparatus 101 is set to the target box of the present embodiment (from the setting screen shown in FIG. 13 to the range of the monitoring target box and the box to be used. All of the print data of the logged-in user can be extracted and printed from all the boxes), so that the user can select the print data for each box and simplify the cumbersome operation of issuing a print instruction as in the past. Can do.

  Conventionally, since a box is used for each user, only the number of users that can be used by the image forming apparatus can use the box. Therefore, when a user uses more than the number of boxes that can be used in the image forming apparatus, one box is shared by a plurality of users. When a single box is shared by a plurality of users, the shared users can print each other's data, and the confidentiality of the print data cannot be maintained.

  In this embodiment as well, a plurality of boxes (the boxes that are the targets of the above-described embodiment) are shared by a plurality of users. However, in this embodiment, only logged-in user data can be extracted and printed. Therefore, the print data is not seen by other users, and the confidentiality of the print data can be maintained for each user.

  Further, in the present embodiment, the box is shared by a plurality of users while maintaining the security as described above, so that the limit on the number of users who can use the box while maintaining the security can be effectively exceeded.

May be. For example, even when a print error corresponding to print data is insufficient (when a color printing agent (for example, color toner, color ink, color ink sheet, etc.) is insufficient), the print data is also skipped. However, monochrome print data may be printed. In addition, printing errors such as when the stapler needle is missing or cannot be used due to a failure, when the bookbinding processing unit cannot be used due to glue breakage or failure, or when the duplex unit cannot be used due to failure, etc. The print data including the print process may be skipped and the print data not including the stapler or the bookbinding process may be printed.

  That is, in the image forming apparatus of the present invention, even if some print data is not printable, if other print data can be printed, the print of the print data that cannot be printed can be skipped and printed. The print data is configured to be printed.

  When the print data is excluded from the print target data in steps S1016 and S1124 and 1125 in FIG. 23B, the print data is moved to the end of the queue (that is, at the end of the print data list (priority is highest). You may comprise so that it may be in a low state)). Further, the print data may be configured to be print data to be interrupted. Furthermore, it may be configured to print using another print resource. For example, the printing process may be changed and the print setting may be changed so that the printing process is not performed on other printing paper, or the stapler process, the bookbinding process, and the duplex printing process are not performed.

  As described above, according to the image forming system of the present embodiment, data stored in the printer (image forming apparatus 101) by a certain user can be output without being known to others (while maintaining confidentiality). A simple image output environment can be constructed.

  In addition, when performing print processing of data stored in the image forming apparatus, it is possible to skip print processing of print data that cannot be printed and output print data of other print data in advance. An environment can be constructed. That is, when performing print processing of data stored in the image forming apparatus, even if print data that cannot be printed exists in the print data instructed to print, the entire print processing is stopped. Therefore, it is possible to print the printable print data in advance.
