In a printer that uses a ribbon 10 (see figure) that transfers an ink layer to a receiving medium, such as a sheet of paper 12 resting against a platen 14, in response to heating action resulting from current supplied to an electrode 16, a complete release of the ink at the heated area must be effected if printing of acceptable quality is to be achieved. The properties that are important in this regard are the release adhesion properties of the ink with respect to the adjacent ribbon layer and with respect to the paper 12. Since the balance among these properties may change with temperature, it proves desirable to remove the ribbon 10 from the paper at a point immediately following the printing point.
