ABSTRACT:
A resistive thermal printer receives dye donor and dye receiver media between a printhead and a platen having an elastomeric surface. The platen and one of the media is wider than the printhead, and the other media is narrower than the printhead, whereby pressure between the printhead and the platen, with the media there between, tends to compress the platen in the region of the narrow medium. End portions of the platen beyond the narrow medium are relieved so as to not be compressed by pressure between the printhead and the platen.
