ABSTRACT:
By counting the number of thermal printer head elements to be energized for each gradation, and adjusting the energizing period on the basis of the counted number, a common energizing period is obtained in order to prevent density unevenness which would otherwise occur because of differences in the number of head elements to be energized for each gradation.
