A thermal printer includes a printer body, a thermal printhead installed in the printer body, a print ribbon installed in the printer body, and a control circuit for controlling the thermal printhead and the print ribbon. The print ribbon has regions of colored dye, regions of resistant overcoating, and regions of stampable overcoating capable of accepting an ink stamp. The print ribbon can be supplied as two exchangeable ribbons, one having colored dye and regions of resistant overcoating, the other having regions of stampable overcoating. The control circuit controls the thermal printhead and the print ribbon to print pictures having stampable images. An ink stamp can be externally applied to a stampable overcoating layer of the picture, an intermediate resistant overcoating layer protecting the image from damage.
