ABSTRACT:
A thermal transfer printer for printing images and patterns on a card with thermally transferable color inks while moving the card back and forth in such a state that the card is held and urged against a thermal print head through an ink ribbon by capstan and platen rollers. In printing, the card is first forwarded over a print-starting point, end then, reversed until the leading end thereof arrives at an overrun stop point prescribed before the print starting point, and thereupon, moved forward until the leading end of the card is positioned at the print-starting point to start printing. Thus, mechanical clearance giving rise to backlash essentially possessed of mechanical elements can be completely eliminated, thereby enabling remarkably high-quality color images to be produced.
