Ribbon reversing mechanism in a high speed printer (telecircuitry) including a ribbon driving stepping motor and a print head drive motor both incrementally driven by pulses from the telegraph circuit. The gear ratios in the ribbon drive train are chosen to ensure that the ribbon is advanced in increments different than the increments of print head movement. The ends of the ribbon are provided with eyelets which are sensed by a mechanism which operates to reverse the ribbon driving motor.
