Abstract

The current consumption and the heat produced in the printhead of thermal printer are mainly governed by total printing dots and printing time for each line. Simple algorithm is proposed to optimize the performance of a thermal printhead, which use variable division according to bit-mapped data of its 1 line. And, for protecting the thermal printhead from exceeding heat, I control the heat energy of each microheater(dots) on the thermal printhead through changes in the applied pulse width.
