Abstract

A thermal printer includes a single thermal recording medium interposed between printing paper and a thermal head so that when predetermined energy is applied to the thermal head, colorant on the thermal recording medium is transferred to the paper to print out a desired letter or symbol, or alternatively the printed letter or symbol is removed and erased from the paper because the colorant once transferred to the paper is attached to the colorant on the thermal recording medium. A printing method using the thermal printer is characterized in originally setting printing energy and erasing energy the latter of which is equal to or larger than the former, applying the printing energy to the thermal recording medium to effect printing operation, and applying the erasing energy to the thermal recording medium to attach it to the printed letter or symbol on the paper to remove and erase it from the paper.
