ABSTRACT:
A thermal ink transfer printer comprises a thermal print head including a linear array of resistance elements corresponding to picture elements to be printed along a line path on a record medium, and means for continuously and relatively moving the head and the mediums to each other at a substantially constant speed in a direction perpendicular to the line path and providing a pressure contact between the head and transfer medium and between the mediums. A head control circuit is provided for generating currents in the resistance elements respectively for durations each proportional to the tone value of each of the picture elements.
