In the following description, in order to simplify the description, when the user A calls the users B, C, and D to hold the conference, the conference materials prepared by the user A are stored in the users B, C, and D. It is assumed that printing is performed by a printer. At this time, it is assumed that users B, C, and D are permitted to print.

  FIG. 1 is a diagram when a user ID and print data are registered in a printer in the printing system of the present invention. At this time, the printer 2 registers a database (hereinafter referred to as instruction information) instructing permission or prohibition of printing based on the user ID given to the users B, C, and D and the identification information (N001) specifying the electronic document file 6. DB) 11, a print data storage unit (print data storage unit) 13 that stores the electronic document file 6 converted into the print data 8 in association with the identification information (N001), and the electronic document file 6 An identification information generation unit (identification information generation unit) 10 for generating identification information for specifying the document file 6 and a control unit (control unit) 12 are configured.

  Here, the terminal device 1 of the user A converts the electronic document file 6 into the print data 8 and transmits it together with the user name list 3 to the printer 2 via the communication unit 4 and is identified by the identification information generation unit 10 in the printer 2. A case where information is generated and registered in the DB 11 together with the user ID will be described. When registering a user ID and identification information, the target electronic document file 6 is converted into print data 8 by the data converter 7. At the same time, when the user A selects and inputs the user IDs of the users B, C, and D who are permitted to print the electronic document file 6 from the user name list 3, the user A is transmitted to the printer 2 through the communication unit 4 together with the print data 8. . The printer 2 receives the data via the communication unit 9 and the identification information generation unit 10 generates identification information (N001) from the print data. On the other hand, since the user ID is also input from the communication unit 9, the control unit 12 registers the user ID and the identification information in the DB 11 in association with each other. The print data is separately stored in the print data storage unit 13 together with the identification information. Further, the generated identification information is transmitted to the user A via the communication unit 9, and the identification information received via the communication unit 4 is stored in the identification information storage unit 5.

  FIG. 2 is a diagram for explaining the operation of distributing data from the user A to the users B, C, and D in preparation for printing. The same components will be described with the same reference numerals as in FIG. When the user approaches the conference, the user A distributes data by e-mail so that the users B, C, and D attending the conference can print and bring the conference materials. That is, the identification information (N001) stored in the identification information storage unit 5 is distributed to each of the users B, C, and D via the communication unit 4 by the mail software 15. As a point here, only the identification information is sent without sending the document file itself. The data is received by the communication unit 18 of each user via the network 16 such as a LAN. For example, the user B will be described. The mail data received by the communication unit 18 is analyzed by the mail software 19 and developed into the mail text 17. Since the mail text 17 includes the identification information (N001) 17a, the identification information storage unit 20 stores the identification information (N001) 17a. The same operation is performed for the users C and D. Thereby, each user can print the material associated with the identification information (N001) from the print data stored in the printer 2.

FIG. 3 is a diagram for explaining the operation of printing the print data permitted by each user. The printer 2 further includes a document selection unit that selects predetermined print data from the print data storage unit 13 and supplies the selected print data to the printing unit 23.

For example, taking user B as an example, user B has previously received material identification information (N001) from user A and stored in identification information storage unit 20 as described in FIG. Of course, the user ID is output from the user ID 21, and the data is analyzed by the printing software 22 and transmitted to the printer 2 via the communication unit 18 via the network 16. The printer 2 receives the data via the communication unit 9. The control unit 12 reads the matrix 11a (instruction information) registered in the DB 11, and analyzes whether or not the user ID is permitted to print the print data corresponding to the identification information (N001). As a result, when the control unit 12 recognizes that the user B can print the identification information (N001), print data associated with the identification information (N001) stored in the print data storage unit 13 is stored in the document. The data is selected and read by the selection means, supplied to the printing unit 23, and the document 24 is printed. Note that a user identification function for printing may be added, and for example, a password for a user ID may be applied. That is, in the above example, when transmitting from the terminal device 14 of the user B to the printer 2, the user B transmits a password for the user ID in addition to the identification information (N001) indicating the target document and the user ID of the user B. The printer 2 performs a password verification procedure and then proceeds to print permission / rejection determination.

For example, the user B operates the input unit 26 of the printer 2 and inputs his / her user ID. When the print data storage unit 13 is designated, a list of document names associated with the print data is displayed on the display unit 25. When the user B selects a document name desired to be printed on the input unit 26, the control is performed. The unit 12 searches the DB 11 based on the user ID and the identification information corresponding to the document name. When the instruction information obtained by the search is prohibited, the printing is not executed and the instruction information is permitted. In this case, the print data associated with the identification information is selected from the print data storage unit 13 and supplied to the printing unit 23, and printing is executed by the printing unit 23.
Further, by partially modifying this embodiment, when the user B transmits only the user ID from his / her terminal to the printer 2 and prints, the user B goes to the printer 2 and prints on the display unit 25. The document name associated with the data may be displayed, and the document may be printed by selecting the document name desired to be printed by the input unit 26. As a result, it is possible to prevent a document printed for a long time from being left at the discharge port of the printer 2 and being viewed by others.

  FIG. 5 is a diagram when a user ID and print data are registered in a printer in a printing system according to another embodiment of the present invention. The printer 2 has a DB 11 for registering instruction information for instructing permission or prohibition of printing based on a user ID given to a user and identification information for specifying the electronic document file, and specifies the electronic document file from the electronic document file.
