Abstract
A thermal head driving system having a plurality of thermal heads, an electric power source commonly used to drive the heads at the same voltage. A pulse generator provided between the power source and each of the heads for producing a driving pulse having a width determined in accordance with a ratio of a resistance value of each thermal head. The plurality of thermal heads are accordingly driven by the respective driving pulses corresponding thereto to effectuate thermal recording.
