Abstract
The present invention is equipped with a plurality of print buffers for inputting print data into a thermal head, wherein such print data are selectively fed to simply change the current on-time for energizing the heating elements of the thermal head relative to specific information out of the entire information to be printed, so that the specific information is printed emphatically in a particular color to become conspicuous, and simultaneously the contour of each specific character is edged in a basic color to be distinctly legible. Such edged print is attained by utilizing the gradient of the temperature distribution induced in the heating elements by the current on-time control system, hence eliminating the necessity of any edging print data to consequently simplify the control.
