A ribbon (22) in thermal printing has an outer layer (50) which adheres to printed characters at somewhat elevated temperatures but is non-tacky at room temperatures. The embodiment has an active layer of an ethylene vinyl acetate copolymer, an acrylic polymer, and carbon black. Thermal printing is conducted from the preferred ribbon by setting the switch (44) for heating to temperatures higher than the lift-off temperature. Lift-off is accomplished by returning to the printing position of the error and setting the switch (44) for lower voltage to the printing electrodes (9). The guide (29) allows cooling so that the bond is set before the ribbon (22) is pulled away.
