Title: THERMAL PRINTER AND THERMAL PRINTER CONTROL METHOD
Abstract:
The purpose of the present invention is to improve the image quality of panoramic printing carried out using a thermal printer. Provided is a thermal printer comprising a junction-shape calculating unit and a control unit. The junction-shape calculating unit divides a panoramic image which is longer than a prescribed print size into a plurality of images which are no more than the print size, and for a panoramic print in which the plurality of images are printed in several parts so that the images are joined, the position and the shape of the junctions between the plurality of images are determined by the junction-shape calculating unit on the basis of an indicator of the difficulty of recognizing the junctions with the human eye. The control unit controls a print medium, an ink ribbon, and a thermal head so that the plurality of images divided on the basis of the position and shape of the junctions determined by the junction-shape calculating unit are each heat transferred to a plurality of continuous regions of the print medium by using a plurality of unit print regions of the ink ribbon, thereby joining the plurality of images.
