本発明は、シリアルドツトマトリックスプリンタのパタ
ーン印字方式に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a pattern printing method for a serial dot matrix printer.

ントヘッドが左から右へ行くときの印字と、右から左へ
行くときの印字とでは、読み出し順序が逆になるのが一
般的である。Conventionally, when reading data from pattern memory and printing with a serial dot matrix printer, the reading order is reversed between printing when the print head goes from left to right and printing when it goes from right to left. is common.
この読み出し方法で印字方向に2ドツト連続しないよう
な処理(以下、間引き処理という)を行なって印字をし
た場合、左から右への印字結果と右から左への印字結果
とが異なる。When printing is performed using this reading method so that two dots are not consecutive in the printing direction (hereinafter referred to as thinning processing), the printing result from left to right is different from the printing result from right to left.

を行なって印字した場合、左から右への印字結果は第2
図(B)に示すようになるのに対し、右から左への印字
結果は第2図(C)に示すようになり、印字結果が異な
る。When printing by performing general thinning from the pattern shown in Figure 2 (A), the printing result from left to right will be the second
In contrast, the printing results from right to left are as shown in FIG. 2(C), and the printing results are different.

徴とする印字方式が得られる。According to the present invention, the present invention includes a pattern memory that generates a character pattern, and a buffer memory that performs pattern thinning processing by reading data from only one direction when reading data from the memory, and temporarily stores the result. Sometimes a printing method is obtained which is characterized in that the buffer memory is read from both directions.
次に、本発明の一実施例を示した図面を参照して、本発
明をより詳細に説明する。Next, the present invention will be described in more detail with reference to the drawings showing one embodiment of the present invention.

る。Referring to FIG. 1, in one embodiment of the present invention, a control circuit 10 reads data from a pattern memory 11 in only one direction, performs thinning processing, and temporarily stores the data in a buffer memory 12. For example, if a pattern as shown in FIG. 2(A) is read from left to right, thinned out, and stored in the buffer memory 12,
2 stores a pattern as shown in FIG. 2(B).
印字処理時にバッファメモリ12からデータを読み出す
ことにより、高速印字を行なうことができる。また、パ
ターンメモリ11からの読み出しを一方向からのみ読み

データとなる。したがって、バッファメモリ12を両方
向から読み出して印字しても印字結果は同一となる印字
品質が向上する。By reading data from the buffer memory 12 during printing processing, high-speed printing can be performed. Further, since reading from the pattern memory 11 is performed only from one direction, the data in the buffer memory is always the same. Therefore, even if the buffer memory 12 is read from both directions and printed, the printing results are the same, improving printing quality.
本発明の間引き処理で印字すれば、左から右への印字結
果と右から左への印字結果とは、第2図(B)または(
C)のいずれかのパターンに統一することができる。If printing is performed using the thinning process of the present invention, the printing result from left to right and the printing result from right to left are as shown in FIG. 2 (B) or (
It is possible to unify the pattern to one of C).
以上説明したように、本発明によれば、高速化のための
間引きパターン印字において、両方向印字結果を同一に
することができ、間引きパターンによる高速化印字の印
字品質を向上できる。As described above, according to the present invention, it is possible to make the printing results in both directions the same in thinning pattern printing for high speed printing, and it is possible to improve the print quality of high speed printing using thinning patterns.
