Abstract

PURPOSE:To make the speed-up of printing speed possible, by a method wherein printing is carried out by opening the dot interval in the horizontal direction by not less than 2 dots spaces in the case of a standard printing speed and at the same time by the structure consisting of combination of 2 dots of up and down lines, in which those up and down 2 dots are slipped by not less than one dot spaces in the horizontal direction. CONSTITUTION:The travel speed of printing head 1 is made to be able to be exchanged by 3 times the standard printing speed and at the same time the drive timings of wires 2... and wires 3... are changed. That is, the horizontal line 20 by which letters or the like to be printed are constructed, is expressed by a combination of dots 21... and dots 22... of two lines neighboring vertically each other. At the same time, the up and down dots 21..., 22... are not arranged mutually on the vertical same line and either dot (the lower dot 22 in an example given in the figure) is horizontally slipped by each one dot space. Thereby, even if printed by a speed at, for example 3, times the standard printing speed, the printing quality durable enough for practical use can be secured and the and the speed-up of printing can be performed.

A serial wire dot printer equipped with a plurality of wire print heads arranged in two rows in a staggered manner employs a print head 1 as illustrated in FIG. In other words, there are two rows of wires 2 extending perpendicularly to the end surface of the print head 1.
3... are provided so that they can be protruded and retracted, and each wire 2..., 3...

The wires 2 in the row are selectively projected to form a dot, and when the print head 1 has moved horizontally by a distance m, the wires 3 in the second row are selectively projected to form the remaining dots. Hit the dot.

Then, by moving the print head 1 in the horizontal direction, desired characters, symbols, etc. (hereinafter simply referred to as characters, etc.) are printed. FIG. 3 shows an example in which the letter F is printed, but in order to simplify the drawing, the number of dots is less than the actual number. In FIG. 2, 6 is a character generator, and this character generator 6 stores dot patterns corresponding to characters to be printed. The dot pattern is sent to the image buffer 8 by the central processing unit 7, and then sent to the wire 2 and the image buffer 8 via the drive circuit 5.

By the way, in order to improve print quality, it is generally good to set the print head 1 to a standard print speed. The standard printing speed is the printing speed when printing so that the dot spacing is equal in the vertical and horizontal directions, which is called "letter quality" in pseudo typefaces. It is possible to perform high quality printing.

ところが標準印字速度では印字ヘッド1の移動速度が遅

However, a drawback of the standard printing speed is that the movement speed of the print head 1 is slow. For this reason, the movement speed of the print head 1 is doubled for data processing purposes.

In this case, since the driving cycle of the wires 2, 3, etc. cannot be changed due to the mechanism of the print head 1, the printing speed (carriage feed speed) is doubled.

Therefore, the number of dots in the horizontal direction is halved, leading to a decrease in print quality. Therefore, as illustrated in FIG. 4, two rows of dots 11 adjacent to each other in the vertical direction are arranged on a horizontal line.
, 12..., and the so-called draft mode, which improves printing quality, has been put into practical use.

However, if the printing speed is increased to three times the standard printing speed, the number of dots in the horizontal direction will be "/3" (every two dots) compared to the standard mode, as shown in Figure 5. However, if the horizontal line is short, the printing quality will be significantly reduced, as it will appear as a mere dot.For this reason, we believe that increasing the printing speed to three times the printing speed is practically impossible. This has been a barrier to increasing printing speed.

The present invention was made based on the above circumstances, and its purpose is to prevent the print quality from significantly deteriorating even if the printing speed is increased to three times that of the standard mode, making it practically possible to increase the printing speed. The object of the present invention is to provide a printing method for a dot printer that achieves the following.

The gist of the present invention is, for example, on-wires arranged in two rows in a staggered manner or a plurality of ink jet nozzles,
When driving a dot printer with a print head such as multiple heating elements, the print head is moved horizontally at a higher speed than the standard print speed, and the horizontal dot spacing is reduced to 2 dots compared to the standard print speed. At the same time as above, the horizontal line of the characters to be printed should be formed by the combination of the upper and lower two rows of dots that are adjacent to each other, and these upper and lower dots should be aligned in the same column in the vertical direction. The method is to print by shifting one dot or more horizontally by one dot or more.

According to the above printing method, one of the dots making up the horizontal line is shifted by at least one dot to the right or left, so even if the horizontal interval between each line is two dots apart, the lines appear to be almost continuous. It will look like a line,
This can prevent deterioration in print quality. Therefore, printing speed can be further increased compared to the conventional draft mode. Furthermore, a conventional print head can be used as the print head itself.

An embodiment of the present invention will be described below with reference to FIGS. 6 to 9 in the case where it is applied to a serial wire dot printer. FIG. 6 shows an example of characters F printed by the method of the present invention. This character can basically be printed using a wire dot printer equipped with the conventional print head 1 shown in Figs. 1

22..., and the upper and lower dots 21..., 22... are not placed in the same row in the vertical direction, but only one of the dots (in the illustrated example, the bottom The dot 22) is shifted horizontally by one dot. Note that the printed characters are actually printed using one tray of vertical 24-dot print heads as shown in Figure 1, and the characters are more detailed and of higher quality than the example shown in the figure. Above, the number of dots is reduced to make it easier to understand.

As mentioned above, the upper and lower dots 2 that make up the horizontal line

Horizontal lines also appear to be continuous lines, and printing quality can be improved.

The print command signals 31..., 32... are output in synchronization with the position signal 33... which is periodically output from an encoder or the like according to the horizontal position of the print head 1. Therefore, the position of the second dot 22 relative to the first dot 21 can only be selected in the following three ways. That is, the position shifted one dot to the left as shown in Figure 6, or the position shifted one dot to the right as shown at the bottom of Figure 8, or the position directly below the first dot 21... There are three ways. Therefore, for example, characters with diagonal lines, such as the letters M and W, are difficult to compose.
This is achieved by adopting an asymmetric dot arrangement along diagonal lines as illustrated in FIG. 9, thereby achieving print quality sufficient for practical use. Even in this case, the dot spacing in the horizontal direction is two or more dots apart compared to the standard printing speed. Therefore, even if the print head 1 is moved at a speed three times the standard printing speed, the driving cycle of the wire can be sufficiently followed.
