ABSTRACT:
A postage meter which includes a thermal print head for printing indicia, postal value, and the like is disclosed. In accordance with the invention, thermal elements in the thermal print head are electronically pulsed in appropriate serially time patters to provide a complete thermally transferred image on a strip moving past the thermal head. A reversible stepper motor and cam arrangement are utilized to provide a drive mechanism and a means for relieving pressure on the strip at the end of each print cycle. With the pressure relieved, a particularly simplified loading of a thermal ribbon cassette may be effected.
