  FIG. 4 is a block diagram illustrating a configuration of the image forming apparatus. The image forming apparatus 14 includes an external memory interface 80 that connects an external memory 16 in which an electronic document and a user program are stored, a compatibility determination unit 82 that determines compatibility of a user program stored in the external memory, and a user An input unit 84 for inputting an instruction, a display unit 86 for displaying a dialog regarding print settings on the display, a drawing processing unit 88 for drawing an electronic document to be printed, and drawing data processed by the drawing processing unit 88 And a control unit 92. The printing unit 90 prints an electronic document on the basis of the control unit 92. The control unit 92 holds the original program of the image forming apparatus itself, prints the electronic document using the original program, and prints the electronic document using the user program stored in the external memory 16.

  Next, printing of the image forming apparatus according to the first embodiment will be described. FIG. 5 is a diagram illustrating a display example of a print dialog according to the first embodiment. In the first embodiment, when printing the electronic document stored in the external memory 16, the control unit 92 displays a print dialog as shown in FIG. 5 on the display unit 86.

  The print dialog 100 includes a document selection group 102 for selecting an electronic document to be printed, a check box 114 for selecting whether or not to use a user program, a copy number designating unit 116 for designating the number of copies, and printing of the electronic document. The print button 118 is instructed, and can be operated with a button of the input unit 84, a touch panel, or a pointing device such as a mouse.

  The user designates the location of the electronic document to be printed in the external memory 16 in the directory designation unit 104, or opens a child dialog that hierarchically displays the data in the external memory 16 by operating the browse button 106. The location can be indicated. The document name display unit 108 displays a list of electronic documents in the location specified by the user in the directory specification unit 104 and displays the currently selected electronic document with a thick frame. The currently selected document can be designated from the input unit 84. The user program name display unit 110 displays the name of the user program associated with each electronic document in the document name display unit 108, and the validity display unit 112 displays whether the user program is valid in this apparatus. To do. For example, in the case of a document “in-house instruction”, “monochrome printing” is associated as a user program, and this user program is compatible and “valid” is displayed.

  Next, the compatibility determination operation in the image forming apparatus 14 will be described with reference to the flowchart of FIG. First, when the external memory 16 is connected to the external memory interface 80, the control unit 92 searches for an electronic document stored in the external memory 16 (step S101). Next, it is determined whether there is a user program associated with the electronic document (step S102). If it is determined that there is no user program, the display unit 86 displays “None” in the user program name 110 of the print dialog in accordance with an instruction from the control unit 92 (step S103). For example, as shown in FIG. 5, when the document name is “estimate”, the user program is displayed as “none”.

  When the user program exists, the display unit 86 displays the program name 50 (see FIG. 3) stored in the user program as the user program name 110 (step S104). For example, in FIG. 5, if the document name is “contract document A”, “authentication printing” is displayed as the user program name.

  Next, the compatibility determination unit 82 extracts the execution format ID of the user program, and determines whether or not the execution format of the user program can be processed in the image forming apparatus 14 (step S105). When it is determined that the execution format of the user program cannot be processed, the display unit 86 displays “incompatible” on the validity display unit 112 of the user program in accordance with an instruction from the control unit 92 (step S106).

  When it is determined that the execution format of the user program is processable, the compatibility determination unit 82 further extracts the input format ID and output format ID of the user program, and determines whether the input and output formats can be processed. Is determined (step S107). When it is determined that the input and output formats cannot be processed, the display unit 86 displays “invalid” on the validity display unit 112 of the user program (step S108). For example, in the print dialog shown in FIG. 5, “authentication print”, which is the user program name of the document name “contract A”, is displayed as “invalid”.

  When it is determined that the input and output formats are processable, the display unit 86 displays “valid” on the validity display unit 112 (step S109), and ends the process. For example, in the print dialog of FIG. 5, “monochrome print” which is the user program name of the document name “internal instruction” is displayed as “valid”.

  In this way, by displaying the compatibility of the document name searched for to be printed and the user program associated therewith in the print dialog, the user confirms whether or not the user program can be used. Printing instructions can be given.

  When the user operates the check box 114 to instruct whether or not to use the user program, and further designates the number of copies in the number of copies designation unit 116 and presses the print button 118, the control unit 92 draws the drawing. The electronic document and the user program are sent to the processing unit 88.

  The drawing processing unit 88 converts the electronic document into the input format of the user program as necessary, and processes the converted electronic document with the user program. The drawing processing unit 88 converts the output format of the user program into print data and sends it to the printing unit 90. The printing unit 90 performs printing using the print data.

  According to the first embodiment, since a compatible user program is executed from the external memory 16, the following effects can be obtained.

(1) The user can use the same user program for different printing apparatuses after confirming compatibility.
(2) No external server is required, and the work of registering the user program in the external server in advance is unnecessary.
(3) Since the user program is executed after confirming compatibility, it is more secure.
(4) Since the electronic document and the user program are stored in association with each other, the customization content can be designated for each document to be printed. For example, when a selected document is printed, a print restriction function that always requires user authentication can be added.
(5) If the external memory is removed, the user program does not exist in the image forming apparatus, so that the customized printing state does not remain when the next user uses it.

  Next, printing according to the second embodiment of the present invention will be described. In the second embodiment, unlike the first embodiment, the user program is not associated with the electronic document and is stored independently. Further, the second embodiment enables a printing function in which a plurality of user programs are combined with an original program held by the image forming apparatus itself. The configuration of the image forming apparatus according to the second embodiment is the same as that of the first embodiment.

  FIG. 7 shows a print dialog in the second embodiment. As in the case of the first embodiment, when the external memory 16 is connected, the control unit 92 searches the electronic document and user program stored in the external memory 16 via the external memory interface 80, and displays the display unit. A print dialog 140 is displayed at 86.

  The print dialog 140 includes a document selection group 142 for selecting an electronic document to be printed, a preview unit 144 for previewing the print result of the selected electronic document, and functions of the original program (original function) of the image forming apparatus.

  The program selection unit 174 opens a child dialog for hierarchically displaying data in the external memory for designation by the directory designation unit 188 for the user to designate the location of the user program in the external memory, and designates the location. And a user program display unit 192 that displays a list of user programs that are determined to be compatible by the compatibility determination unit 82 shown in FIG. 4 among the user programs in the external memory. The user can select the user program listed in the user program display unit 192 as a pre-processing or post-processing program for the original program. The selected user program is displayed on the pre-processing user program display unit 180 or the post-processing user program display unit 184.

  If the order in which the programs are executed is different, the print result may be different. For example, when the user program “stamp character 1” is selected as the preprocessing program, “stamp character 1” is displayed on the preprocessing user program display unit 180 as shown in FIG. “Original function 2 UP” is displayed, and the print result display unit 186 displays the electronic document with 2 UP after the stamp character is pressed on each page.

  In contrast, when the user program “stamp character 1” is selected as the post-processing program, “stamp character 1” is displayed on the post-processing user program display unit 184 as shown in FIG. “Original Function 2 UP” is displayed in 182, and an electronic document in which stamp characters are pressed on each page after 2 UP is displayed in the print result display unit 186.

  The user program can be selected as pre-processing or post-processing of the original program, or can be selected as both pre-processing and post-processing. Further, the same user program may be selected and specified twice or more. The user program and the original program are preferably displayed in the processing order according to the user's instructions.

  Next, the compatibility determination operation of the image forming apparatus according to the second embodiment will be described with reference to the flowchart of FIG. First, when the external memory 16 is connected to the external memory interface 80, the control unit 92 searches for an electronic document and a user program stored in the external memory 16 (step S201). The compatibility determination unit 82 extracts the program ID of the detected user program, and determines whether or not it matches the preset ID (step S202).

  If it is determined that the program IDs match, the execution format ID is extracted, and it is determined whether or not the execution format of the user program can be processed in the image forming apparatus 14 (step S203). If it is determined that the execution format can be processed, the input and output format IDs are extracted, and it is determined whether the input and output formats can be processed (step S204). If it is determined that the input and output formats can be processed, the control unit 92 displays the program name on the user program selection unit 174 shown in FIG. 8 (step S205), and ends the process.

  Next, a method for specifying a user program by the user will be described.
