Abstract
A dual mode thermal printer has two modes of operation, i.e., a multi-color recording mode and a monochromatic recording mode. The thermal printer includes a thermal printhead provided with a plurality of resistor elements which are functionally divided into a plurality of blocks, each preferably having the same number of resistor elements. During the multi-color recording mode, the plurality of resistor elements are activated in accordance with image data on a block-by-block basis; whereas, during the monochromatic recording mode, at least two blocks of the plurality of resistor elements are activated at the same time.
