  When a confidential document is printed by PC printing, if it is printed in the same manner as a non-confidential document, there are the following problems. That is, if printing is performed with a setting that is different from the printing error or intention, printing is performed again. It is not preferable to print a confidential document many times, which increases the possibility that it will be seen by others.

  In addition, it is necessary to perform a special process for a confidential document printed in error, such as by applying a shredder (in order to maintain the confidentiality of the document) as compared with a normal print output. Therefore, it is desirable to print out the confidential document as few times as possible.

  As in Patent Document 1, an idea has been proposed in which an erroneous print output is suppressed by displaying an image preview on the image forming apparatus. However, when this idea is implemented, there is a risk that an image on the image forming apparatus can be seen from the side by another person who happened to be near the image forming apparatus.

  In the technique of Patent Document 2, when printing a specific image from a portable terminal, the image is printed when a reduced image is sent for portable use and then a print instruction is issued from the portable terminal. When such processing is performed, documents other than confidential documents are also displayed each time, and there is a problem that the processing becomes complicated in the case of normal printing. In addition, there is a problem that displaying the information every time may cause the user to give a print instruction without understanding the necessity of confirmation, and the meaning of confirmation will be lost.

  Hereinafter, an image processing apparatus according to an embodiment of the present invention will be described. The image processing apparatus is provided in the image forming apparatus.

  [First Embodiment]

  FIG. 1 is a diagram showing an apparatus configuration of an image forming system according to the first embodiment of the present invention.

  Referring to the figure, PC 101 and MFP 107 are connected by a network such as the Internet 103. An IC card reader (card reader) 105 is connected to the MFP 107. A printer driver for sending print data (job) to the MFP 107 is installed in the PC 101.

  The PC 101 includes a display 101a, a CPU / ROM / RAM 101b, a storage unit 101c, a communication unit 101d, and an input / output device 101e.

  The MFP 107 includes a scanner 107a, a printing unit 107b, a control unit 107c, a display / input unit 107d, a storage unit 107e, and a communication unit 107f.

  By executing the computer program stored in the storage unit, the RAM, and the ROM with the CPU and the control unit, the PC and the MFP can function as an information processing apparatus. A printer driver is stored in the storage unit 101c of the PC 101 and operates on the RAM 101b. Printing by the MFP 107 can be executed by sending print data from the PC 101 to the MFP 107 by the printer driver. The MFP 107 has a function of printing a print document sent from the PC 101.

  When the IC card reader 105 is used, a confidential document can be printed as follows. The MFP 107 that has received the PC print job from the PC 101 temporarily stores the PC print job in the MFP. When the user who has transmitted the print job holds the IC card (C) over the IC card reader 105, the MFP 107 recognizes the user who owns the IC card. The MFP 107 prints a PC print job corresponding to a user who owns the IC card (a user registered in association with the ID of the IC card). That is, after reading the IC card, the printing process is automatically performed.

  An MFP can be set on a display / input unit (panel) 107d of the MFP 107. The display / input unit 107d displays the status of the MFP.

  Note that printing may be performed when a confidential document is selected on the display / input unit 107d and an instruction to perform printing is received.

  The MFP 107 has a function of receiving an image sent from a PC, a function of forming an image in the form of electronic data, a function of printing out the formed image, and an image formation instruction from the PC via a printer driver. And a function for performing print setting and image formation processing, and a function for performing the above-described print processing based on a print instruction from a PC via a printer driver.

  The PC 101 has a function of instructing that an image instructing printing is an important document such as a confidential document by a printer driver and a function of transmitting data to be printed to the MFP. Print data is sent from the application software in the PC to the printer driver.

  Further, when the print instruction from the PC indicates that the document is an important document, the MFP 107 sends the image formed in the form of electronic data to the PC so that the image to be printed can be obtained using the PC. And a function of forming an image when a print instruction is issued from the PC after sending.

  In this way, it is possible to ask the user using the PC whether or not the formed image can be printed. When the user instructs that the image can be printed as a result of the inquiry, the image is printed on the MFP. Instructions are sent.

  In this way, only when the document is an important document such as a confidential document, a preview image is created by the image forming apparatus and confirmed by the user. By confirming the print output only when it is really necessary, there is an effect that it is possible to perform a print while maintaining the confidentiality of the confidential document while minimizing a complicated process on the user side.

  Further, only when an IC card of a user who executes a print job is read by the IC card reader 105, a function (touch and print function) for executing a print job by the MFP is used. By executing it when it is instructed that the image is an important document image, the confidentiality of the document can be maintained.

  If it is not instructed that the image is an important document image, the system may be configured not to use the touch and print function.

  The MFP 101 has a function of accepting print cancellation from the PC. Data to be printed is sent to the image forming apparatus without waiting for an instruction from the user. When a print cancel instruction is issued from the user, the MFP is notified of print cancel.

  Further, when a print instruction is issued by the MFP, display of the formed image displayed to the user for confirmation on the PC 101 is canceled.

  FIG. 2 is a diagram illustrating a printer driver setting screen of the PC 101.

  This screen is displayed on the display 101a of the PC 101 when the printer driver is activated. That is, when the PC 101 is instructed to start a PC print job via an application, a printer driver screen 201 is displayed on the PC 101. The user who uses the PC makes settings on this screen and issues a print instruction by clicking the print button 205. When the cancel button 207 is clicked, printing is canceled.

  On the screen 201 of the printer driver, the user can set the paper to be used and the number of copies to be printed. The printer driver screen 201 includes a setting unit 203. When the user checks the setting unit 203, a setting for performing confidential printing and a setting for performing touch and print can be performed.

  When the confidential print setting is performed, the touch and print may be automatically set. When the touch and print setting is performed, the confidential print may be automatically set.

  When the confidential print is set, after the user confirms the print image, a process of accepting an input to execute or cancel the print is performed.

  When touch and print is set, the print job is executed by the MFP only when the IC card of the user who executes the print job is read by the IC card reader 105.

  In this embodiment, it is assumed that touch-and-print is automatically set when the confidential print is set.

  FIG. 3 is a diagram showing a screen for allowing the user to confirm the print image when the confidential print is set.

  When executing the confidential printing, an image display window 301 as shown in FIG. 3 is displayed on the PC 101. The image itself to be printed is displayed page by page in the display area 303. When the page feed button 305 is clicked, the page of the image displayed in the display area 303 is sent first or later. Thereby, when printing a plurality of originals, the contents of the image to be confirmed can be switched. In the printing condition display area 307, printing conditions are displayed.

  When the print instruction button 309 is clicked on the PC, the MFP can print. When the print cancel instruction button 311 is clicked, a job discard instruction is issued to the MFP.

  FIG. 4 is a diagram illustrating a processing sequence in the image forming system when the confidential print is selected.

  When the user issues a print instruction on the screen of FIG. 2 from the PC (S901), print data is sent from the printer driver to the MFP (S903). The MFP creates image data for preview by processing the print data (S905), and sends it to the printer driver (S907). For example, an image file of PDF (Portable Document Format) is created and sent to a printer driver. Thereafter, the MFP interrupts the process and enters a standby state (S913).

  Upon receiving the image data, the printer driver displays it to the user (S909) and inquires whether or not to print (S911). When printing, a message to that effect is sent to the MFP (S915). The MFP resumes the interrupted printing, and if a valid IC card is read, performs printing (S917). Thereby, a printed output is provided to the user (S919).

  If printing is not performed, the fact is transmitted to the MFP, and the MFP discards the interrupted job. When a valid IC card is read and printing is performed, or when the interrupted print is resumed, a message to the effect of print is sent from the MFP to the printer driver.

  FIG. 5 is a flowchart showing processing executed by the printer driver operating on the PC.

  Referring to the figure, if the start of the print job is accepted from the application software in step S101, the printer driver screen (FIG. 2) is displayed in step S103. When execution of printing is instructed, it is determined in step S105 whether or not “confidential print” is designated. If YES, a print job is transmitted to the MFP as “confidential print” in step S107. In response to this transmission, the MFP receives image data (image data of a print job scheduled to be printed) created by the MFP and transmitted to the PC.

  In step S109, an image display window (FIG. 3) is displayed. In this window, the image data received in step S107 is displayed (reference numeral 303 in FIG. 3). In step S111, the user inputs a “print” or “do not print” instruction, and transmits it to the MFP.

  In step S113, when the fact that there is a print instruction from the MFP is received, the display of image data (reference numeral 303 in FIG. 3) in the image display window (FIG. 3) is deleted in step S115. Note that this erasure may be performed immediately after the process of step S111.

  If the print job is not a confidential print job in step S105, the print job is transmitted to the MFP in step S117.

  6 and 7 are flowcharts showing the print job processing executed by the MFP.

  In step S201, when the MFP receives a print job, in step S203, it is confirmed whether or not the print job is a confidential print. As a result of the confirmation, if it is not a confidential print (NO in S203), the print process (or the process related to the print) is performed as it is in step S217.

  As a result of the confirmation, if the print job is a confidential print (YES in S203), image processing of the print job is performed in step S205 to enable printing. Thereafter, the image data is sent to the PC in step S207. Note that the processing in step S203 and the processing in step S205 may be interchanged.

  After the image data is sent to the PC, a response is waited for the image data in step S209. In step S211, it is confirmed whether or not the response has come from the PC. If NO, it is determined in step S213 whether or not the waiting time has timed out (whether there has been no response within a predetermined time). If NO in step S213, the process returns to step S209.

  If “YES” is determined in the step S213 (no response is received from the user within a predetermined time), the process proceeds to a step S219, the print job is discarded, and the print process is not performed thereafter.

  If a response is received in step S211, the content of the response is confirmed in step S215. If the response content is “print”, print processing is performed in step S217. If the response content is “do not print”, the print job is discarded in step S219, and no print processing is performed thereafter.

  FIG. 8 is a flowchart showing the contents of the print (printing) process (S217) of FIG.

  This is a process of performing print output when an instruction to print a confidential print job is input on the panel (display / input unit) 107d of the MFP.

  When the correct IC card is read by the IC card reader 105 in step S301, the fact that the MFP has issued a print instruction is transmitted to the PC in step S303, and the user's PC print corresponding to the IC card is transmitted in step S305. Print out the job. Thus, printing can be started after the user confirms at a place where the image forming apparatus is located.

  The printing mechanism (such as “touch and print”) is a known technique and will not be described in detail here.

  The MFP does not perform print output unless the IC card reader reads the IC card by the processing of FIG. When the user reads the IC card into the IC card reader, the MFP notifies the printer driver of the PC that the job will be printed (step S303 in FIG. 8). At this time, if the display 303 of FIG. 3 is made, the display is deleted (step S115 of FIG. 5). It is determined that it is not necessary to display the print image of the confidential document on the PC. At this time, it is assumed that the user who wants to print is not in front of the PC. Therefore, it is possible to prevent a third party from seeing a confidential document by erasing the image on the PC.

  [Second Embodiment]

  Since the apparatus configuration of the image forming system in the second embodiment of the present invention is the same as that in the first embodiment, description thereof will not be repeated here.

  According to the second embodiment, when the MFP is instructed that the document is an important document for the print instruction from the PC, after the image formation instruction is issued from the PC, the print instruction is further issued from the PC In addition, it has a function of forming an image.

  In the printer driver of a PC, when an image to be printed is instructed to be an important document such as a confidential document, an image to be printed is formed with electronic data, which is sent to a user who uses the PC. Display and inquire whether or not to give a print instruction.

  FIG. 9 is a flowchart illustrating processing executed by the printer driver of the image forming system according to the second embodiment.

  In FIG. 9, the processes in steps S401 to S405 and S409 to S417 are the same as the processes in steps S101 to S105 and S109 to S117 in FIG.

  In step S407, the print job is transmitted to the MFP, and the print data is set as image data in the printer driver. The image data is displayed on the image display window in step S409.

  FIG. 10 is a flowchart illustrating processing executed by the MFP of the image forming system according to the second embodiment.

  In FIG. 10, the processing in steps S501 to S513 is the same as the processing in steps S201 to S205 and S209 to S213 in FIG. In FIG. 10, the process of transmitting the image data in step S207 of FIG. 6 to the PC is not necessary. This is because the image data is created by the printer driver.

  [Third Embodiment]

  Since the apparatus configuration of the image forming system in the third embodiment of the present invention is the same as that in the first embodiment, the description thereof will not be repeated here.

  In the third embodiment, image processing is performed on the printer driver side, and after previewing it, the printer driver makes an inquiry about whether to print or not. A PC print job is transmitted to the MFP only when there is an answer to print “Yes”.

  FIGS. 11 and 12 are flowcharts showing processing executed by the printer driver of the image forming system according to the third embodiment.

  In step S601, when the printer driver receives an instruction to print a print job from the user, in step S603, the printer driver checks whether the print job is a confidential print. As a result of the confirmation, if it is not a confidential print, the PC print job is sent to the MFP as it is (S615).

  If the print job is a confidential job as a result of the confirmation, the image data of the print job is displayed to the user by displaying an image display window 301 as shown in FIG. 3 on the PC 101 in step S605. Note that the display process here does not have to be performed by the printer driver itself, and the application software may display by performing a process in which the printer driver calls the application software.

  After previewing the image in this way, in step S607, a response from the user to the image data is waited for.

  In step S609, it is confirmed whether a response has been received from the user. If NO, it is determined in step S611 whether the waiting time has timed out (whether there has been no response within a predetermined time). If NO in step S611, the process returns to step S607.

  If “YES” is determined in the step S611 (no response is received from the user within a predetermined time), the process proceeds to a step S617, the print job is discarded on the printer driver side, and the print process is not performed thereafter.

  If there is a response in step S609, the content of the response is confirmed in step S613. If the response content is “print”, PC printing is instructed by sending the job to the MFP in step S615. If the response content is “do not print”, the print job is discarded in step S617, and no print processing is performed thereafter.

  [Modification 1]

  In FIG. 6, after image processing is performed in step S205, print processing is performed in step S217. In the MFP, if the IC card is not read by the IC card reader by the processing of FIG. In the process of FIG. 8, when the user instructs the MFP to “do not print”, the process may proceed to step S219 in FIG. 7 to discard the job.

  [Modification 2]

  In step S203 of FIG. 6, YES may be determined only when the print job is a “confidential print” job and an instruction to print out using special paper (specific print paper) is given. Confidential documents are highly important documents and are considered to be printed frequently on specially formatted paper. By performing the process of this modification, it is possible to prevent wrong printing on a specially formatted sheet.

  That is, the preview display is performed only when the confidential document is printed on a specific print sheet. Accordingly, it is possible to prevent misprinting when the final tax return document is printed on the final tax return sheet, for example.

  Further, in step S203 of FIG. 6, it may be determined only whether or not an image formation instruction using a specific sheet is performed.

  [Modification 3]

  In FIG. 3, when the page feed button 305 is clicked, the page of the image displayed in the display area 303 is sent first or later. Thereby, when printing a plurality of originals, the contents of the image to be confirmed can be switched.

  When an instruction to “print” is issued with the button 309, only the image displayed in the display area 303 may be printed out by the MFP. In this way, only the image confirmed by the person who has instructed to print the image can be printed.

  That is, by printing up to the place where the user has displayed the preview, it is possible to print only up to the place where there is no problem with printing, and it is possible to prevent a printing mistake unexpected by the user.

  [Effects of the embodiment]

  As described above, in the above-described embodiment, only when the document is an important document such as a confidential document, the preview image is created by the image forming apparatus or the printer driver, and the print output is confirmed by the user. This is because there are cases where confidentiality is desired and cases where confidentiality is not required. By confirming the print output only when it is really necessary, there is an effect that a complicated process on the user side can be minimized and the confidential document can be printed with confidentiality. Further, by performing printing by “touch and print”, there is an effect that the confidentiality of the confidential document can be further maintained.

  Further, in an important document, the timing of the print instruction and the image preview display are made the same, and when the user issues a print stop instruction after confirming the image preview, the print is stopped. In the case of a document that does not need to maintain confidentiality, it is possible to perform immediate printing, so that the convenience of the user is not impaired.

  Further, when the job is printed by the MFP at the time of preview display on the PC screen, the preview display on the PC is canceled. As a result, it is possible to minimize the time in which the PC is left in a state where the confidential information is previewed on the PC, and security can be maintained.

  [Others]

  In order to realize the touch-and-print function, in addition to the IC card, equipment (such as a magnetic card or a card with code information such as a barcode) that proves the user who has instructed printing can be used. The touch and print function may be realized based on information such as a user's fingerprint.

  In addition, when it is specified that the touch and print function is used, the formed image may be printed, or the user who uses the PC may be inquired and printed as a result of the inquiry. The system may be configured to send a print instruction to the image forming apparatus when the user instructs.

  The present invention can be implemented for an image forming apparatus such as an MFP, a facsimile machine, and a copying machine.

  Further, the processing in the above-described embodiment may be performed by software or by using a hardware circuit.

  In addition, a program for executing the processing in the above-described embodiment can be provided, and the program is recorded on a recording medium such as a CD-ROM, a flexible disk, a hard disk, a ROM, a RAM, and a memory card and provided to the user. You may decide to do it. The program may be downloaded to the apparatus via a communication line such as the Internet.

  In addition, it should be thought that the said embodiment is an illustration and restrictive at no points. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.
