Abstract
Pulse fingers are disposed on a heat-generating material which fingers are pulsed to change the resistance of portions of the heat-generating material. By such change in the resistance of the heat-generating material, electrical current diffusion is prevented and heat diffusion is permitted between the changed resistance portion of the heat-generating material, thereby providing high resolution character printing and so-called 'continuous' graphics printing.
