Method and apparatus for recording used labels

摘要

A thermal transfer printer which includes a labeling media drive subassembly and ribbon drive subassembly which cooperatively advance labeling media and a thermal transfer ink ribbon past a print head subassembly. A labeling media supply spool is rotatably driven by the labeling media drive subassembly to feed labeling media. The labeling media supply spool has labeling media with a plurality of labels on a web wrapped around a spool core. An inventory of labels available for printing on the spool is stored on a memory device. The memory device is electrically connected to printer circuitry in a printer. When the printer prints on a label, the inventory on the memory device is updated to reflect the unavailability of the printed label.
