Abstract

PURPOSE:To efficiently move a printing head to a printing position in a serial printer. CONSTITUTION:A moving quantity calculation means 1 calculates the moving quantity of a printing head in a number-of-dot unit from the present position and printing position of the printing head. A number determining means 2 divides the number of dots by the lateral dod size of a space code to calculate the quotient and the remainder. A first moving means 3 moves the printing head due to code data from the quotient and a second moving means 4 moves the printing head due to a bit map from the remainder.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a printer head moving system, and more particularly to a printer head moving system for moving a printer head of a serial printer horizontally to a printing position.

[0002]

2. Description of the Related Art Conventionally, a printer head moving method of this type moves a printer head by printing a blank character of code data, or prints a blank character of a bitmap data (NULL) to print the printer head. The method of fixing to either one of moving is used.

[0003]

The conventional printer head moving method described above is realized by a method fixed to either code data movement or bitmap data movement. In this case, the size of the blank (space) characters is fixed, so you can only move in units of blanks (spaces), which may cause an error from the actual print position. Has the drawback that it takes a long time to move.

[0004]

A printer head moving method of the present invention is a printer head moving method for moving a printer head of a serial printer horizontally to a printing position. A movement amount calculation means for obtaining the movement amount in dot units,
A number determination means for determining the number of code data and bitmap data for moving the printer head in the horizontal direction from the value obtained by the movement amount calculation means, and a printer based on the code data determined by this number determination means It comprises a first moving means for moving the head and a second moving means for moving the printer head according to the bitmap data determined by the number determining means.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram of an embodiment of the present invention.
In the embodiment shown in FIG. 1, a moving amount calculating means 1 for obtaining a moving amount of a printer head in the horizontal direction to a printing position, and code data for moving the printer head in the horizontal direction from the value obtained by the moving amount calculating means 1 are shown. It is composed of a number determining means 2 for determining the number of bit map data, a first moving means 3 for moving the printer head by the code data, and a second moving means 4 for moving the printer head by the bit map data. It

FIG. 2 is a flow chart of processing in each means of FIG. 1. The flow of processing of the embodiment of FIG. 1 will be described below with reference to FIG. First, the movement amount calculation means 1 subtracts the current horizontal coordinate position of the printer head from the horizontal coordinate of the print position to obtain the amount of movement of the printer head to the print position (step 101), and converts it into the number of moving dots. (Step 102). Next, the number determining means 2 divides the number of moving dots obtained by the moving amount calculating means 1 by the blank (space) code size to obtain the number of characters from the quotient (step 201). ) Subtract the number of dots for the character to obtain the number of remaining dots (step 2
02). Next, when the number of blank characters obtained by the number determining means 2 is not 0, the first moving means 3 outputs a printer control sequence for Kanji out (KO) (step 301), and subsequently. Number determination means 2
Space code of the space (space) character obtained in (20
(h) is output to the printer (step 302). Then, the second moving means 4 outputs the printer control sequence of bitmap output when the number of dots for moving the printer head based on the bitmap data obtained by the number determining means 2 is not 0 (step 401), and the number determining means. The bitmap data NULL corresponding to the number of dots to be moved by the printer head is converted to (00
Output h) to the printer (step 402).

By performing the processing by the above four means, the data output to the printer is optimized in order to move the printer head in the horizontal direction to the print position, and it is possible to move in dot units. Become.

[0009]

As described above, according to the present invention, by optimizing the printer control sequence for horizontally moving the printer head to the printing position and the data for the movement, the printer head can be moved. There is an effect that waste can be omitted from the output data, the printer head can be moved in units of todds, and an accurate amount of movement can be set.
