Abstract
A thermal head has a heating element array with a plurality of heating elements disposed in line and a head driver. The head driver drives the heating elements at the same time in accordance with each set of heating data of 8 bits to record dots of one line on a recording sheet. In printing dots by using heating data of 9 bits, a heating data divider circuit divides the 9-bit heating data into two series of 8-bit converted heating data. By using these two series of the 8-bit converted heating data, two heating sequences are continuously executed. Each heating element is heated by the two heating sequences as many times as that corresponding to the heating data.
