A THERMAL HEAD DRIVING SYSTEM ABSTRACT OF THE DISCLOSURE A thermal transfer printing system for printing data on a medium employing a plurality of aligned heat elements has a memory for receiving data and a driver for driving or energizing selected ones of the heat elements to print the stored data in a timed sequence which prevents preheating of certain heat elements. In one arrangement, upon driving the heat elements, every other heat element is first driven or energized to print the respective data, and then the remainder of the heat elements are driven. After all heat elements are energized according to the data to be printed, a stepping motor is actuated and the medium is advanced in preparation for printing a next line of data.
