Abstract
A printer is provided with a controllable bail located between a print station and a downstream paper tear-off station. Upon occurrence of a first control signal, a printed portion of the paper is advanced to a desired tear-off position adjacent the tear-off station. Thereafter (after a predetermined time delay or after operator switch actuation), the paper is retracted to a new first print line position at the print station. The intermediately located bail is released at least after the leading edge of the paper is retracted thereunder and until sufficient paper is again advanced (e.g. during new printing operations) to ensure that paper is again located between the printing platen and the bail before the bail is re-engaged.
