ABSTRACT:
A thermal transfer printer including a thermal head for generating heat in accordance with a desired print pattern, a platen having a surface for supporting an ink-sheet and paper, the ink-sheet and paper being pressed by the thermal head on the platen surface so that ink from the ink-sheet is transferred to the paper, a paper supply for storing and supplying paper, an ink-sheet supply and drive for storing and supplying an ink-sheet, the ink-sheet supply and drive driving the ink-sheet to move in accordance with the movement of the paper, a paper drive arranged between the platen and the paper supply, the paper drive driving the paper by the required length according to the position of the paper relative to the position of the platen, and a paper tension device for applying suitable tension to the paper at least between the platen and the paper drive so that the length by which the paper drive drives the paper is identical with the length by which the paper moves on the platen. Since the length by which the paper moves on the platen corresponds only to the length by which the paper drive drives the paper, the length by which the paper moves on the platen can be correctly controlled through the paper drive.
