ABSTRACT:
A resistive thermal printer has a platen drive mechanism which includes (1) a thermal printhead having an array of selectively-activatable thermal elements and (2) a rotatably-driven platen roller opposed to the printhead and forming a nip with the printhead through which a receiver medium is driven by the platen roller while the thermal elements are selectively activated. The platen roller has an outer layer of perfluorinated polymer. The platen roller includes a compliant layer below the outer layer of perfluorinated polymer.
