Sheet feeding accessories for a typewriter-type printer unit having a stepwise driven print roller. The single sheet feeder is pivotally mounted on the printing unit and the continuous sheet feeder is mounted piggyback style on the single sheet feeder. A drive belt commonly connects the print roller, the single sheet feeder, and the continuous sheet feeder. take-off (60,61) is provided down stream in the direction of printing media movement. Both a single sheet conveyor (15) and a continuous form conveyor (30) attached to conveyor 15 are driven by a drive belt 21 commonly interconnecting the drive roller (12), the drive take-off (60,61) with the sheet and forms conveyor to achieve synchronous operation in the same feed direction. The drive take-off (60,61) has rollers of such a circumference in engagement with the printing media so as to maintain tension on the printing media when fed therethrough.
For use with an electromechanical printer (10) of the type having a print unit in which printing media (55,65) is moved through the printing unit by a stepping drive roller (12) and in which a drive take-off means (60,61) is provided down stream in the direction of printing media movement:
