Abstract
A thermal transfer printing system of the kind having a plurality of resistive elements substantially aligned for printing an image line-by-line includes a resistance value variation detector selectively connected to each of the resistive elements in order to derive compensation data based upon resistance variations in such elements. The resistant compensation data is retained in a memory at addresses corresponding to each of the resistive elements in the printing head and the compensation information is read-out from the memory to thereby compensate the printing data prior to being fed to the thermal printing head.
