Abstract

PURPOSE:To obtain a printer controller capable of printing a printing paper with a mark which can be discriminated from sideways when the printed papers are stacked, by developing a side mark into dots on a side mark dot memory, synthesizing the mark in a full-dot memory, and printing the mark. CONSTITUTION:A main processing circuit 4 edits one page in a page buffer 5, and gives a dot development command to a printing processing circuit 6 through a printing data development command line 14. When the development of one page is completed, the circuit 4 sets a side mark resistor counter 10 at an initial stage, and gives a command for synthesis of a side mark to the circuit 6 through a side mark synthesis command line 13 on a page basis. On receiving the side mark synthesis command, the printing processing circuit 6 reads from rasters in a side mark dot memory 1 designated by the side mark raster counter 10, and develops the same raster N-times at an upper part and both side parts of a full-dot memory 7. By this, the content of a list can be indicated at the side of the list simultaneously with outputting the list.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a printer control device.

[Conventional technology]

Conventional printer devices generally perform only two-dimensional printing, such as in Japanese Patent Laid-Open No. 112234/1983 and general printer devices.

[Problem that the invention seeks to solve]

Conventional printers can only print two-dimensionally, so when stacking output printer paper, it is impossible to check the contents without opening the printer paper, making it difficult to store and manage the output printer paper. Improvements are required in this area.

SUMMARY OF THE INVENTION An object of the present invention is to provide a printer control device that prints a print that can be recognized from the side when stacking printer paper sheets when outputting a list.

[Means for solving problems]

The above object is achieved by a side mark cluster counter and a side mark dot memory.

[Effect]

Recently, laser beam printers have become popular.

Laser beam printers can print on any part of printer paper. Items printed on the perforations on the printing side can be read from the side when the perforations are folded.

In addition, if the printing extends beyond both sides of the paper, it is possible to read it by the misalignment of the paper when stacked together. By printing on the perforations on the surface and on both sides of the paper so that it slightly protrudes, it is possible to form characters that are legible when viewed from the sides when the paper is piled up. Memorize the printed content in the side mark dot memory, and use the side mark dot counter to
Performs raster control on a page basis.

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to FIG. When the main processing circuit 4 receives the roadside mark code 16 from the host computer 1, the main processing circuit 4 edits the command character string into a character address, stores it in the page buffer 5, and sends it to the print processing circuit 6 as a side mark expansion instruction line. 15, a side mark dot memory 11 head dot development instruction is given.

The print processing circuit 6 obtains a phantom pattern of 90 characters from the character pattern address in the page buffer 5 and develops it into a side mark dot memory 11.

Upon receiving the write command, the main processing circuit 4 edits one page into the page buffer 5, and instructs the print processing circuit B to develop dots through the print data development phase line 14. When the development of one page is completed, the main processing circuit 4 initializes the side mark cluster counter 10 through the side mark cluster counter initial setting line 12, and sends the side mark cluster counter 10 to the print processing circuit 6 through the side mark composition instruction line 13 for each page. , instructs to synthesize side marks.

When the print processing circuit 6 receives a side mark composition instruction, it reads out the raster in the side mark dot memory 11 indicated by the side mark raster counter 10 and develops the same raster N times on the upper side and both sides of the full dot memory 7. Then, the raster whose side mark raster counter 11 has been increased by 1 is read out from the side mark dot memory, and the same raster is expanded into N rasters on the lower side of the full dot memory. When the development of one page including the side marks is thus completed, the print processing circuit 6 reports the completion to the main processing circuit 4.

The main processing circuit 4 that received the completion report sends the printer adapter 8
Upon receiving the output instruction, the printer adapter 8 reads the dot data from the full dot memory 7 and outputs it to the printer 8.

The above process is repeated for each page by the number of rasters in the side mark dot memory.The reason why the side mark raster counter is not updated on a page basis is to print the same raster across the perforations of the paper.

〔Effect of the invention〕

According to the present invention, since the contents of the list can be displayed on the side of the list at the same time as the list is output, handwriting becomes unnecessary and storage management of the list becomes easier.
