ABSTRACT:
Thermal printing apparatus has an impression roller mounted in opposition to a thermal print head, the mounting for the impression roller permitting movement of the impression roller toward and away from the thermal print head and the impression roller having a part cylindrical surface and a planar surface. Prior to a printing operation the roller is positioned with its planar surface co-planar with a feed bed. An actuator projects from the planar surface so as to be engaged by a leading edge of a print receiving medium entered between the impression roller and the print head. Engagement of the actuator rotates a drive gear for the impression roller into driving engagement with drive means.
