ABSTRACT:
A thermal printing apparatus comprises a thermal head which has a plurality of heat generating elements to generate a heat according to an image. A temperature of the thermal head is detected by a thermister. The thermal head is controlled by a thermal head controlling circuit which comprises a heat storage computing circuit for estimating a stored heat in the thermal head after the present driving signal will be supplied to the thermal head to generate heat. The pulse width of the driving signal is varied using the detected temperature of the thermal head, the modified pulse width and the estimated stored heat as the stored heat in the thermal head is increasing or decreasing during printing the present element.
