ABSTRACT:
A printing apparatus for printing designs, halftones, alphanumeric and other printed matter on sheet material utilizes a thermal printhead that is pressed against sheet material on a roller platen during a printing operation. A donor web bearing an ink material is interposed between the printhead and the sheet material on the roller platen. In order to improve the print quality, the printer includes a pressure regulating mechanism which not only controls the pressure between the printing head and roller platen at different pressure levels but also allows the printing head and platen to be separated and moved away from one another.
