Thermal printing device, method for printing an image using said printing device and system for printing an image

摘要

A printing device that includes a platen for supporting an imaging member during a printing operation and at least one print head subassembly for direct thermal printing on the imaging member. The print head subassembly is configured to be movable independently of the platen for printing on a first surface of the imaging member in a first transport path and on a second surface of the imaging member in a second transport path. The printing device also includes an element movable with said print head subassembly for ensuring that the wrap of the imaging member around the platen is substantially symmetrical about the print line such that the thermal heating elements of the thermal print head are substantially parallel to the surface of the imaging member when printing on each side of the imaging member.
