Abstract: The invention intends to obtain a good printed result without creating displacement of printing positions when printing is performed on a piece of printed paper with different contact pressures of the thermal head to the platen. To achieve the object, the thermal transfer printer of the invention comprises control means that make it possible to select a contact pressure of the thermal head to the platen in correspondence with a printing mode, and controls a printing setting position in accordance with the printing mode selected, whereby it becomes possible to correct the drifts of printing positions due to the difference of contact pressures of the thermal head to the platen, and acquire an excellent printed result without having the drifts of printing positions.
