Abstract
A paper rewind roll drive for printers of the type in which the paper strip is advanced for both line spacing and to bring the last printed line to the viewing station and is thereafter retracted to position the next print line at the printing station, the drive comprising means for enabling the rewind roll to retract incrementally at the start of a print cycle, and a one-way drive effective after the usual paper advance following a printing operation to impel the rewind roll in an advancing movement with sufficient force to cause it to overtravel and thus take up any slack in the strip brought about by the usual line spacing advancement or otherwise.
