Abstract

PURPOSE:To omit a troublesome setting process such as superimposition of a sign and a character pattern, by controlling a printing position of a sign pattern relative to a character pattern together with the size and number of signs or the like according to the contents of horizontal and vertical direction control buffers. CONSTITUTION:Synchronously with a clock signal, a character pattern signal 12 is stored from a hot system 11 into a line bit buffer 13, and reading from a horizontal direction control buffer 18 is simultaneously performed. A vertical direction control buffer 20 reads vertical positions of signs to be printed, in response to a counter 21 having counted up the clocks, by one line. Data on each position obtained from the buffers 18, 20 are inputted to an AND circuit 22, whereby the position of sign data on a two-dimensional printing surface is determined. A sign pattern corresponding to the position is read from a sign pattern memory 16, and is inputted to an OR circuit 14 for ORing the sign pattern with a character pattern read from the line bit buffer 13, and the OR data is outputted to a printer.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a printing control device that prints a symbol pattern superimposed on a character pattern.

[Conventional technology]

FIG. 3 is a block connection diagram showing a conventional printing control device disclosed in, for example, Japanese Unexamined Patent Publication No. 58-119040.
In the figure, 11 is an upper system such as a host computer, 3
1 is an adder that stores the storage address of the symbol pattern memory; 62 is an adder that stores the storage address of the character pattern memory; 33 is a comparator; 34 is the symbol pattern/memory;
35 is a character pattern register, 36 is a shift register for serially converting the parallel addition data of the symbol pattern and character pattern, 37 is an address counter, and 38 is a pixel register for updating the address and setting the parallel data of the shift register 66. .

Next, the operation will be explained. When printing a character pattern and a symbol pattern in a superimposed manner, first, a character code indicating the first address of the symbol pattern is set in the adder 31, and a character code indicating the first address of the character pattern is set in the adder 32. n, and the number of dots indicating the width of the character pattern is set in the comparator 36 tL. When printing, a clock signal (CL) is input from the outside.
While counting up K) with the address counter 67, the symbol butter/memory 34 and the character pattern mesori 65 are counted up.
are read out into respective symbol patterns and character patterns 71, the logical sum of these two patterns is carried out, and a pattern obtained by superimposing the two patterns is sent to the printing device via the shift register 36t, and printed. . This operation is performed by the comparator 36.

Repeated for the number of dots in the character pattern. The next superimposition of character pattern and symbol pattern is repeated for one line in the same manner.

[Problem that the invention seeks to solve]

Since the conventional printing control device is configured as described above, the symbol pattern code and the width information of the character pattern are sent for each character at the overlapping seno of the symbol pattern and the character pattern. When printing toner marks, job marks, logos, etc., it is necessary to set the symbol pattern code, character pattern, etc. It is necessary to set t sets of code and character pattern width information, and there are problems such as complicated processing and slow processing speed.

This invention was made in order to solve the above-mentioned problems, and it is possible to overlay an arbitrary number of symbol patterns on a character pattern at an arbitrary position on a page, in an arbitrary size, or as only a symbol pattern. The purpose is to provide a printing control device 1 capable of printing.

[Means for solving problems]

The print control device according to the present invention includes a Klein bit buffer for storing character patterns t1 in line units, a symbol pattern memory for storing symbol patterns, a duty direction control buffer for printing position t-IJ of the symbol pattern, and a horizontal direction buffer, each character pattern and symbol pattern read from the line bit buffer and the symbol pattern memory are added by an adder, and a symbol pattern t of an arbitrary size is placed at an arbitrary position on the printing paper.
It is designed to be printed over the above character pattern.

[Effect]

In this invention, the print position, size, and number of symbols are set in the vertical control buffer and horizontal control buffer by a host computer or other host system, and these are read out in synchronization with the printing operation, and based on this set data. The symbol pattern read from the symbol pattern memory is outputted in a manner such that it is accurately superimposed on the character pattern read from the line bit buffer in a predetermined positional relationship.

Next, the operation will be explained. The symbol pattern to be used is loaded in advance from the host system 11 into the symbol pattern memory 16, and the horizontal direction control buffer 18. Print control information is loaded into the vertical direction control buffer 20.

When the printing operation starts, the character pattern signal 12 is sent to the host system 11 in synchronization with the clock (CLK) No. 4.

The symbol pattern to be stored is stored in the symbol pattern memory 16.
This and the character pattern read from the line bit buffer 16 are input to the OR circuit 14 to perform a logical sum t.

Output to a printing device.

The printing example shown in FIG. 2 will be explained. Here, in the water direction control buffer 18 and the vertical direction control buffer 20, for example, rAJ, rB
J, rcJ are written, and "0" is written in the area not to be printed. At this time, the corresponding symbol pattern stored in the symbol pattern memory 16 is printed only in the area where the value of the water direction control buffer 18 and the value of the vertical direction control buffer 20 are equal. In the figure, ■, ■, ■ indicate printing positions on the printing paper 40, and 41 indicates a perforation.

Although the types of symbol patterns are not shown in the above embodiments, if the capacity of the symbol pattern memory 16 is large, a plurality of symbol patterns can be printed. Further, in the above embodiment, the case where the control pulse unit is one dot unit is shown, but if control is performed in units of multiple dots, the symbol pattern memory 16° horizontal direction control buffer 18. The capacity of the vertical direction control buffer 20 can be reduced.

〔Effect of the invention〕

As described above, according to the present invention, the printing position of the symbol pattern relative to the character pattern is controlled by the contents of the horizontal direction control buffer and the vertical direction control buffer, as well as the size and number of symbols. , it is possible to omit troublesome setting processing such as overlapping symbol patterns and character patterns, and the hardware can be simplified, resulting in an inexpensive device.
