发明名称 Heat control method of a thermal head
摘要 There is provided a heat control method of a thermal head which can achieve even printing of high quality by conducting area control so that heating elements of the thermal head may not be uneven in print density in the arrangement direction, and more particularly, which controls the heat amount of a thermal head having a plurality of heating elements arranged in a row on a substrate by controlling the current supply time of the heating elements of the thermal head, divides the heating elements into a plurality of control groups a in the direction of the row, sets virtual control groups on both ends of the row, and controls the heat amount of the thermal head by performing control so as to level the differences in temperature among the control groups.
