Roll-paper printing apparatus, printing control program, and printing control method

A non-transitory recording medium storing a computer readable printing control program that operates in a roll-paper printing apparatus including a paper feeder that feeds roll paper, a printer that forms an image based on a job on the roll paper, an image scanner that scans the image formed on the roll paper, and a reeler that reels the roll paper, the printing control program causing the roll-paper printing apparatus to perform:

• acquiring the image scanned by the image scanner from the roll paper and detecting an abnormal output in comparison between the image based on the job and the scanned image;
• and
• determining whether output of the job continues or stops, in accordance with a previously set condition,
• wherein, in a case where the roll paper is cut in a passage direction of the roll paper into a plurality of lanes arrayed in a width direction of the roll paper, the determining includes continuing, in a case where the abnormal output is detected on a lane, the output of the job.
