ABSTRACT:
An ink ribbon cassette includes two rotatable bearings for respective spools, a drive system for alternately rotating one or the other of the two bearings so that a ribbon extending between the spools positioned on the bearings will be moved in opposite directions depending on which bearing is being rotated, and a control system for controlling which bearing is being driven by the drive system based on actuation by respective trip elements on the ribbon near its opposite ends.
