Abstract

In a resistive ribbon printer in which a column of electrodes on a thermal printhead applies heat to the ribbon to produce print horizontal white streaks, which occur in dark data due to overfeed ing of paper relative to the electrodes during a vertical index, are eliminated by using an additional electrode at the top of the column of electrodes and energizing it when the top eight electrodes of the column are energized.
