A thermal dot type printing apparatus includes a thermal head having N heating elements arranged in a line, a head driver which allows a current to selectively flow through the heating elements in accordance with N-bit dot data, and a control circuit for sequentially supplying a plurality of N-bit dot data constituting the character data to be printed to the head driver. This printing apparatus further has a counter for counting the total number of heating elements energized by the head driver in a unit time. The control circuit supplies a control signal in accordance with a count data of the counter to the head driver, thereby reducing the current which is supplied to the heating elements upon printing operation.
