リンタ。[Scope of Utility Model Registration Claim] (1) Mixed characters such as logical negation symbols, overlines, vertically enlarged characters, standard size characters, and underlines, etc. mixed on the same line, and the upper half of overlines and vertically enlarged characters , the lower half of the vertically enlarged character, the standard size character, and the underline are divided vertically into four parts, the character pattern corresponding to these divisions is read out from the character font generation circuit, and this character pattern is modified. This is a dot matrix printer that writes each line into an image buffer and then reads out this line to print.The image buffer is used to store overline patterns and upper half patterns of vertically enlarged characters. for,
It consists of four individual image buffers, one for storing the lower half pattern of vertically enlarged characters, one for storing the standard size character pattern, and one for storing the underline pattern.
A dot matrix printer characterized by being able to complete mixed printing of lines. (2) The dot matrix according to claim (1), characterized in that two groups of four individual image buffers are provided, and each group is alternately switched and used for each line of mixed printing. printer.
