Abstract

PURPOSE:To print a horizontal straight line clear by dividing it into a plurality of times. CONSTITUTION:When a printing hammer 1 on a hammer bank 2 is oscillated over the range as shown by the shuttle action 3 and driven at the timing at each printing position 4 to print a horizontal straight line, the printing is done in by division into two shuttles: First, a printing 5 is done at an interval of one dot and then, a printing 6 with the subsequent shuttle to stop a resulting gap. This halves the response speed of a printing hammer 4. having the power consumption thereby preventing the lowering of the power source voltage.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a print control system for a dot line printer having a shuttle mechanism.

Conventionally, in this type of dot line printer.

When printing long straight lines in the horizontal direction, such as horizontal ruled lines, a large number of printing hammers had to respond simultaneously and continuously, which resulted in a drop in the power supply voltage of the hammers, and the printing quality of horizontal lines deteriorated. The present invention is a printing method that solves the above-mentioned drawbacks by dividing horizontal straight lines into multiple prints and making it possible to clearly print horizontal straight lines. .

When checking the received data and detecting that the data includes a straight line in the horizontal direction, the one dot line is divided into multiple prints to reduce the response speed of the hammer and reduce the power supply voltage. This prevents deterioration and enables clear printing of horizontal straight lines.

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 shows a principle diagram of a dot line printer, in which a plurality of printing hammers 1 mounted on a hammer bank 2 swing over a range shown in a shuttle motion 3, and the printing hammers are moved at the timing of each printing position 4. is driven to perform printing operation.

When printing horizontal straight lines such as horizontal ruled lines, the printing hammer 1 must perform printing operations at all printing positions, but as shown in Figure 2, the printing is divided into two shuttles, and the printing is done first. If we use a method in which printing 5 is performed every other dot, and printing 6 is performed to fill in the spaces between them with the next shuttle, the response speed of the printing hammer 4 will be halved and the power consumption will be halved, so '<m' It can also prevent pressure drop,
Clear printing results can be obtained.

In this way, the received data is checked in advance to determine whether a horizontal straight line is included in the print dot row, and depending on the result, printing is performed in one shuttle or in two shuttles. Decide what to do.

Although I have written an example in which printing is performed with two shuttles when it is determined that the data includes a straight line, it is even more effective if this is printed with two or more shuttles.

As explained above, the present invention can greatly improve the printing quality by dividing and printing a horizontal straight line in a plurality of times.
