ABSTRACT:
A technique and structure for resistive ribbon thermal transfer printing including a separate resistive ribbon and transfer ribbon therefor is illustrated. The resistive ribbon is used only for the generation of heat and is placed in contact with a separate transfer ribbon including a very thin carrier ribbon coated with ink. A moveable electrode printhead generates a heat pattern along the resistive ribbon and this pattern is compressed along the direction of printing by means of printhead motion v.sub.1. The resistive ribbon is moved relative to the transfer ribbon at a velocity v.sub.2 so as to generate a heat flow in the transfer ribbon corresponding to the pattern required for normal printing. The ink is melted and is transferred from the transfer ribbon to the paper.
