ABSTRACT:
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 at least one driving roller for driving the imaging member during the printing operation that is configured to drive the imaging member through a driving nip created by the driving roller with a substantially constant degree of wrap wherein the distance of transport of said imaging member for a given angular rotation of said driving roller is substantially the same for the first transport path and the second transport path.
