Abstract
A thermal head model type determining apparatus for a thermal printer having a print engine containing a replaceable thermal head and a printer controller for controlling the print engine. The thermal head model type determining apparatus includes a memory for storing model type information tables containing property data for each of a plurality of different thermal head model types, a measuring circuit for measuring properties of a thermal head provided in the print engine, a and thermal head model type identifying device for determining the model type of the thermal head provided in the print engine by comparing the properties measured by the measuring circuit with the model type information tables stored in the memory.
