An arrangement is described and shown in Fig. 1 in which the paper bail of a printer is closed by the same drive that indexes the platen. Platen 1, shown in Fig. 1, is driven by platen gear 2 that is affixed to the platen shaft. The platen drive gear 3 is engaged with the platen gear and causes platen rotation. The bail cam and gear assembly 4 is also mounted on the platen shaft, but is free to rotate. The bail arm assembly 6 is spring-loaded by spring 5 against the platen. Fig. 2 is the normal state, in which the platen can be driven in either direction and the paper bail is against the platen. When a sheet of paper 8 is inserted to the pinch 9, the paper bail 7 is then manually pulled to an open position.
