  • Patent number: 8616794
    Abstract: In a printer that prints to continuous paper, starting to backfeed the recording paper for printing the next print job before the user cuts the previously printed page can be prevented. The printer prints while conveying recording paper delivered from fanfold paper through a transportation path, and after printing cuts the recording paper using a cutter disposed near the paper exit. When printing ends, the control unit positions the perforation at the trailing end of the printed page to a cutting position, and sets a tear-off state holding the recording paper where positioning was completed. When new print data is received while in the tear-off state, the recording paper transportation operation is prohibited and the tear-off state is continued until a preset delay time passes. When the delay time has passed, the recording paper is immediately fed back and indexed for the next print job.
