Abstract

PURPOSE:To find easily the duplicated or missing output page of a cut sheet by setting a counter which counts the sequential order of output pages and printing the count as a page number in the specific area of a sheet, in a cut sheet printer which edits and prints print data from a host computer in units of page. CONSTITUTION:A counter which counts the sequential order of output pages is provided and the count is printed as a page number in the specific area 21 of a sheet 20, in a cut sheet printer for printing print data from a host computer edited in units of page. In addition, a mark which expresses the identity of the page whether it is a page sent again to the printer, is put with a page number. Consequently, it is possible to find whether the output page of a cut sheet is duplicated or missing easily.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a printer control device, and more particularly to a method for easily determining duplication or omission of output pages of a cut sheet printer.

[0002]

2. Description of the Related Art Conventionally, for example, Japanese Unexamined Patent Publication No. 61-26628.
As described in No. 5 Printer, when a jam is detected, printing is stopped and the jammed paper is removed. When the jammed paper is removed, the print restart command returns to the page that could not be printed due to the jam and restarts printing.

In the above method, it is impossible to check the printed result to see if there is a page duplication or missing due to a jam.

[0004]

When a paper jam occurs in a cut paper printer, the printer interrupts printing. The operator restarts the printing after removing the paper accumulated in the printer. This process is called jam recovery. In such a case, when it is attempted to check whether the paper is continuously continuous, it is extremely difficult to make a judgment when the page number is not included in advance in the page.

There are various factors that cause jams, and the location of the jam begins when one sheet is pulled out from the hopper.
There are various places until entering the stacker. Also, the number of sheets on the sheet feeding path of the printer when a jam occurs is different. It is desirable to be able to easily check the continuity of pages due to jam occurrence and jam recovery in these various cases.

For example, in the case of sending one page data to a printer and instructing to print 100 copies, if each page must be given a different page number, it is no longer possible to instruct copying. There's a problem. It is appropriate to generate such a number on the printer side.

An object of the present invention is to print consecutive page numbers on a cut sheet output, and to duplicate output pages due to a jam,
The goal is to make it easy to check for any omissions.

[0008]

In order to achieve this object, a means for printing the page number generated by the printer controller at the corner of each page is provided.

Further, there is provided means for printing a special mark on the first page when the paper inside the printer is removed and restarted when a jam occurs. The page numbers are checked, and if they are consecutive, there is no problem, but the printing of the mark means a warning that the page numbers should be checked especially in the vicinity thereof.

Whether to output such additional information depends on a command from the host. You may want to use it only for maintenance and operation check. In addition, there are cases where the user does not like the output of such supplementary information even when used for normal print output.

[0011]

[Function] The additional information output format is 9 (n) or P
(N) JR. n is a page number, and it is desirable that the maximum count number be at least larger than the number of pages retained in the printer. JR indicates that the page is the first retransmitted page for jam recovery.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS.

FIG. 1 shows the connection between the host and the printing apparatus 10. The printing device includes a printer control device and a printer. The data from the host is once stored in the printer control device and then sent to the printer page by page. Figure 2
Is an output example on the cut sheet 20. Additional information (P (n)
Alternatively, P (n) JR is printed at area 21. The print data of the user is printed in the print effective area 22.

FIG. 3 shows how to make page numbers in the printer controller. The page data from the host is stored in the page buffer 30 from the left, such as 1 page and 2 pages. It is assumed that there is an instruction 31 for making two copies on the third page. If this page is sent to the printer by single-sided printing as an example, as shown in the page sending sequence 32, (1), (2), (3) from the left are in ascending order. This number becomes the page number P (n) of the incidental information printed on the output paper. There are only two buffers for page send sequence 32. One is preparing the next page to be sent and the other is sending the page to the printer.

FIG. 4 shows a case where a jam occurs. Up to 7 pages of data are coming from the host to the page buffer 30. On the other hand, as shown in the page sequence 32, it is assumed that a jam occurs (at the mark 42) when a sheet is instructed to be pulled out from the hopper in order to send page data to the printer. Assuming that the number of times that the paper has entered the stacker correctly is three, there is a stacker pointer at the position indicated by arrow 44, and four pages obtained by subtracting (4) from the jam pointer (8) are on the paper transport path of the printer. There will be. These four pages (45 brackets)
The sheet of paper) is removed by the operator. The page to be retransmitted is the page (4), but on the page buffer 30, the third page from 7-4 = 3 is the page to be retransmitted. If you look at the final output, you will see the Jam Recovery mark on the 4th page.

[0016]

According to the present invention, since the page number and the resending page mark for jam recovery are printed out as additional information on the cut sheet output, it is easy to visually detect duplication or omission of pages.

[Brief description of drawings]

FIG. 1 is a diagram illustrating a connection configuration between a host and a printing apparatus.

FIG. 2 is a diagram illustrating a cut sheet output example.

FIG. 3 is a diagram showing how to create a page number to be printed at a corner of a page as supplementary information.

FIG. 4 is a diagram showing how pages are retransmitted when a jam occurs.

[Explanation of symbols]

21 ... Supplementary information (page number and page resending page mark when jammed), 30 ... Page buffer (numerical value shows page number), 32 ... Page sending order (during single-sided printing).

Claims (3)

[Claims] 1. A cut sheet printer that edits and prints print data from a host page by page, and a counter that counts the order of output pages is provided, and the counter is used as a page number to print in a specific area of a sheet. Printer control device. 2. The printer control apparatus according to claim 1, wherein a mark indicating whether the page is a page retransmitted to the printer is added together with the page number. 3. The printer control device according to claim 1, wherein whether or not to print the page number or the mark is designated by a command from the host.
