Abstract

PROBLEM TO BE SOLVED: To provide a printer capable of determining a page number when resuming printing on the basis of a page number of a page printed lastly before stopping the printing.SOLUTION: A printer 1, arranged between a print portion 11 for printing images and a paper discharge portion 2b, comprises: a camera 13 that optically reads out page numbers printed on a print object 2d printed by the print portion 11; a spool portion 12 that stores an intermediate file of each page; and a printer control portion 10 that, when resuming printing after stopping the printing, obtains a page number using the camera 13 and then refers to the spool portion 12, searches for an intermediate file corresponding to a page number following the page number obtained using the camera 13 from unprinted intermediate files and resumes the printing using the searched intermediate file.

Description

  The present invention relates to a technique for guaranteeing continuity between a page printed so far and a page after resuming printing when a printed matter having a plurality of pages is printed by a printer.

  When a printed matter with multiple pages (for example, a form) is being printed by the printer, if a failure such as a paper jam occurs in the printer, the printer is paused and printing is resumed after the failure is cleared. In the case of a printed matter that prints for each page, it is necessary to confirm that the continuity between the page printed up to that point and the page after resuming printing is maintained.

  As a conventional technique for confirming the continuity of pages after resuming printing, the conventional technique disclosed in Patent Document 1 includes the number of pages that have been printed and the number of signals input from the printer or paper discharge stacker (the number of pages stored in the paper discharge stacker). ), A page number for resuming printing is determined in the printer control device, and printing is resumed from this page number when printing is resumed.

JP-A-11-227987

  However, since the above-mentioned prior art determines the page number at the time of resuming printing based on the number of signal inputs from the printer or the paper discharge stacker, if there is an error in the number of signal inputs from the printer or the paper discharge stacker, it is incorrect. There was a risk of resuming printing from the page number.

  Therefore, an object of the present invention is to provide a printer and a printing restart method that can determine a page number at the time of resuming printing based on the page number of the page printed last before stopping printing.

  A first invention that solves the above-described problem is a camera that is installed between a print unit that prints an image and a paper discharge unit, and that optically reads a page number printed on a printed matter printed by the print unit, The spool part that stores the intermediate file of the page, and the page number obtained by using the camera after obtaining the page number using the camera when resuming printing after stopping printing A printer comprising: a printer control unit that searches the intermediate file corresponding to the next page number in the unprinted intermediate file and resumes printing using the searched intermediate file .

  In the second invention, when the printer resumes printing after stopping printing, the page number is optically read from the printed matter by using a camera installed between the print unit for printing an image and the paper discharge unit. The intermediate file corresponding to the page number next to the page number acquired using the camera is searched from the unprinted intermediate file by referring to the stage and the spool unit storing the intermediate file of each page. And resuming printing using the searched intermediate file. A method for resuming printing of a printer.

  According to the above-described present invention, since the page number at the time of resuming printing is determined based on the page number acquired using the camera installed between the print unit for printing an image and the paper discharge unit, printing is stopped. The page number at the time of resuming printing is determined based on the page number of the page printed last.

1 is a diagram illustrating a configuration of a system in which a printer according to an embodiment is arranged. 1 is a block diagram of a printer according to an embodiment. The figure explaining the content which guarantees the continuity of the page after resuming printing.

  From here, preferred embodiments of the present invention will be described. The following description is not intended to limit the scope of the present invention, but is provided to aid understanding.

  FIG. 1 is a diagram illustrating a configuration of a system 2 in which a printer 1 according to the present embodiment is arranged, and is a block diagram of the printer 1 according to the present embodiment.

  The system 2 illustrated in FIG. 1 includes a printer 2 used for printing a printed material 2d (for example, a form) on which a page number is printed for each page, a paper feeding unit 2a that supplies continuous paper 2c to the printer 2, and a printer 2 And a paper discharge unit 2b that winds the printed product 2d printed in a roll shape.

  As shown in FIG. 2, the printer 2 includes a printer control unit 10 that controls the entire printer 2, a spool unit 12 that stores an intermediate file for each page, and a printing unit 11 that prints an image on continuous paper 2c. And a camera 13 that is installed between the printing unit 11 and the paper discharge unit 2b and optically reads a page number printed on a printed matter printed by the printing unit 11.

  The printing unit 11 of the printer 2 performs color printing or monochrome printing on the continuous paper 2c supplied from the paper feeding unit 2a. As a printing method, an electrophotographic method for charging a photosensitive drum or ink droplets is used. An ink jet method for discharging is known. In FIG. 1, the paper used for printing is the continuous paper 2c, but the paper used for printing may be a sheet.

  The intermediate file stored in the spool unit 12 of the printer 2 is a file obtained by converting the submission file of the printed material 2d into the metadata format. The intermediate file format includes Outline PDF (Portable Document Format), JDF (Job Definition Format). ) And EMF (Enhanced Metafile) are famous.

  The camera 13 of the printer 2 is a device that reads the page number from the printed material 2d discharged from the printing unit 11 when the printer 2 is stopped. In FIG. 1, a camera 13 is arranged between the printer 2 and the paper discharge unit 2b for easy understanding. However, in detail, the printer 2 is positioned so that the page number of the printed matter 2d printed last can be read. The camera 13 is arranged.

  The printer control unit 10 of the printer 2 is realized by a computer program. The printer control unit 10 according to the present embodiment uses the print unit 11 to use intermediate files stored in the spool unit 12 in the order of page numbers. In addition to the printing function, when printing is resumed, it has a function for guaranteeing continuity between the page printed so far and the page after printing is resumed.

  FIG. 3 is a diagram for explaining the contents for guaranteeing the continuity of pages after resuming printing. When an operation for resuming printing is performed after printing is stopped, the printer control unit 10 of the printer 2 operates the camera 13 to read the page number from the printed matter 2d discharged from the printing unit 11, and stops printing. A process of acquiring the page number printed last is performed (S1).

  Next, the printer control unit 10 of the printer 2 refers to the spool unit 12 and searches for an intermediate file corresponding to the page number next to the page number acquired using the camera 13 from the unprinted intermediate files. (S2). Since the page number is printed at a predetermined position on each page of the printed matter 2d, it is possible to correspond to the intermediate file by analyzing a font image (for example, an outline font) corresponding to the position where the page number is printed. To get the page number.

  Next, the printer control unit 10 of the printer 2 resumes printing using the searched intermediate file, and this procedure ends (S3).
