ABSTRACT:
A wear-resistant ribbon guide surface (11 or 25a, 25b) is added to a thermal printhead (1) to lower the ribbon exit angle after printing or to shift the ribbon exit position away from the printing. The angle past that surface remains large enough for visibility of prior printing. The modification of exit conditions makes the printing darker and significantly improves printhead life.
