Abstract
A thermal printer comprises a plurality of thermal elements incorporated in a printing head. The thermal elements are pre-heated in dependence on logical product of data derived through inversion of data printed in the preceding cycle and data to be printed in the instant cycle, to thereby prevent excessive temperature rise in the printing head and suppress the power consumption to a minimum.
