ABSTRACT:
In a thermal printer, a print element drive circuit has connected in series a CMOS (Complementary Metal Oxide Semiconductor) inverter gate driving a MOS (Metal Oxide Semiconductor) transistor which in turn drives a bipolar power transistor. The bipolar power transistor provides current pulses to a resistive element which is thermally activated in response to the pulses to cause the printing of characters upon thermal sensitive paper. Character decoding circuitry provides high impedence logic level inputs to the CMOS inverter and these inputs are converted by the printer driver circuitry into corresponding high current drive pulses.
