Abstract

PURPOSE: To eliminate the printing shift of a bidirectional printing type serial printer by a method wherein a transmitting time of a printer driving signal is selected in response to the moving direction of a pinter head.
CONSTITUTION: In a right direction printing, by method wherein a signal REV from a processor 1 is set to "0", a differential signal (b) formed through an encoder 10, a differential circuit 11, an AND circuit 12 is selected by a selector 5, a printer driving signal (f) is outputted from a one-shot multivibrator 15 and a character cade CC which has been latched in a generator character 2 is printed. On the other hand, in a left direction printing, by a method wherein the REV is set to "1", the initial value data ID from th processor 1 is written into a programable counter 8 by a differential signal (b) inputted from an AND circuit 3, then a count and signal (c) is selected by the selector 5 and the character code is printed in the same way as the above. Therefore, printing shift is prevented in the double direction printing by means of setting of the initial value ID in respose to printing speed.
