ABSTRACT:
A printing apparatus and method for printing on a record medium utilizing an electric thermo-transfer process. The apparatus includes an ink sheet having an ink layer with heat-fusable ink thereon facing the record medium, and a resistive layer. A print head having at least a pair of opposed electrodes is in contact with the resistive layer. A driving circuit is coupled to the pair of opposed electrodes for applying a voltage to the pair of opposed electrodes. The applied voltage causes a current to flow in the ink sheet to heat the ink layer. A pulse width setting circuit controls the pulse width of the voltage applied to the electrodes to control the position and amount of heating of the ink. The system provides full-color printing on the record medium.
