タ。[Claims for Utility Model Registration] An ink sheet provided with an ink layer, a conveyance means for conveying recording paper to a position of a thermal head, and heating the thermal head to print on the recording paper through the ink layer. In the thermal transfer printer, a dew condensation detection means for detecting dew condensation on the recording paper is arranged near the conveying means, and when the dew condensation detection means detects dew condensation, the thermal head is heated and the fan is rotationally driven. A thermal transfer printer characterized in that it is equipped with a control means for controlling.
