ABSTRACT:
A thermal transfer printer has a thermal print head with a number of thermal print elements which are operated by power electronics and controlled by a control unit to print an imprint on a medium by thermally transferring ink from an inking ribbon to the medium by energization of selected print elements by the control unit, with the inking ribbon and the medium being movably disposed between the print head and a counter-roller with the inking ribbon being unwound from a supply reel and wound onto a take-up reel. The end of the inking ribbon is identified in a method and apparatus wherein the number of imprints produced by said inking ribbon is counted, and a signal is emitted after a predetermined number of said imprints has been counted.
