This article describes a method of achieving a "ribbon-saver" printing mode that is completely mechanical, controlled through carrier motion for a resistive ribbon-type printer. Fig. 1 schematically presents an overall view of the hardware involved. The mechanism that achieves the ribbon-saver function replaces the escapement belt idler pulley bracket (left side of figure), while the mechanism that manipulates it is mounted on the rear of the carrier, as shown. The approach is to pay out ribbon mechanism drive cable as the carrier prints from left to right in order to use less ribbon than would be used if the drive cable were simply fixed to the side plates.
