A thermal transfer printer is capable of printing a plurality of images from one picture block of an ink sheet 34. The thermal transfer printer includes a damage prediction part that makes prediction of damage on a subsequent print image to be generated by printing of a preceding image by predicting damage on the ink sheet 34 to be generated by printing of the preceding image, and a print control part that prints the preceding image while exerting control to suppress generation of the predicted damage on the subsequent print image based on the damage prediction.
