Abstract

PURPOSE:To enhance the printing quality by providing a means for changing the impressed voltage on the thermal head in accordance with the correlation of the contents of the printing patterns and the printing history. CONSTITUTION:In the case of a blank pattern such as pattern 504, R1=O and the step 607 is carried out to discriminate the CNT. In the case where a vertically long pattern has previously been generated and the impressed voltage has been higher than usual, the impressed voltage is returned to the usual value when the vertically long pattern is generated again. For example, the impressed voltage for the pattern 503 is set to be higher than usual, and the impressed voltage is returned to the usual value at the time of pattern 501. The step 604 is carried out for discrimination in the manner described above and for measuring the time elapsed from the instant at which the impressed voltage is raised. When the lapse of time is long, i.e., when CNT=O, the step 605 is carried out to add Vt to a predetermined impressed voltage Vs on the head, and thereafter the register is made at CNT=4.
