<p>PURPOSE:To achieve a precise thermal control to obtain a printing result of high quality. CONSTITUTION:A pre-thermal hysteresis operation circuit 4 and an adjacent thermal influence operation circuit 5 read energy data from an energy data buffer 2 to compute thermal influence correction data being time function. Each correction data is multiplied by energizing timing by means of a correction data operation device 14 and accumulated in an energizing control signal generating device 15. When the accumulated correction data has reached a certain amount of correction, an energizing control signal 15a is outputted and thermal control is performed at an energizing control means 12 or a strobe control means. By handling the thermal control as time functions with respect to energizing timing, thermal control can be performed with high accuracy even in a thermal printer wherein printing feed is performed during energizing, so that printing dots are uniformized and printing density is controlled with high accuracy, resulting in printing of high quality.</p> |
