Resistive ribbon printing is described, for example, in U.S. Patent No. 4,384,797. Heat is generated by the resistivity of the ribbon itself, and this heat causes ink to flow to effect printing. The printhead contains electrodes which contact a resistive support layer opposite the ink layer. This article describes the modification of such ribbons to be durable enough to support multiple printing operations after ink is reflowed on the ink side. Conventional resistive ribbons tend to break with multiple print passes and exhibit degradation of print quality. To reflow a ribbon for multiple use, the ribbon is rewound after printing. A heating element is then brought into pressing contact with the ink layer of the ribbon and the ribbon is rewound.
