ABSTRACT:
A thermal print head has thermal print elements located along an edge of a substrate between two faces thereof. An impression roller resiliently urges a print receiving medium, for example a mail item in a postage meter, into ink transfer engagement with an ink layer of a thermal transfer ink ribbon and urges the ink ribbon into heat transfer engagement with the thermal print elements. The print head is mounted to be adjustable as to location of the line of print elements relative to the impression roller and the angular disposition of the print head. The resiliently pressure exerted by the impression is adjustable. Adjustment of the print head and of the pressure may be effected automatically in response to sensing of compressibility of the print receiving medium.
