Printing apparatus having sheet position control, control method, and computer-readable storage medium

A printing apparatus comprising:

• a conveying roller configured to convey a sheet which is pulled from a roll sheet;
• a printing unit, including a printhead, configured to perform printing on the sheet conveyed by the conveying roller;
• a cover portion configured to open and close with respect to an apparatus body;
• a first detection sensor configured to detect an open state in which the cover portion is opened and a closed state in which the cover portion is closed;
• a second detection sensor configured to detect the sheet on a conveyance path for the sheet by the conveying roller;
• a cutter provided downstream of the printing unit and configured to cut the sheet;
• an operation input unit, including a display, configured to accept a setting indicating whether to cut the sheet in a case of canceling a print job;
• and
• a control unit, including a CPU, configured to control a printing operation including printing on the sheet by the printing unit and conveying the sheet by the conveying roller,
• wherein the control unit interrupts the printing operation if the first detection sensor detects the open state during the printing operation and controls the conveying roller, based on the second detection sensor, to return the sheet to a predetermined position if the first detection sensor detects the closed state afterward, and
• wherein if a setting accepted by the operation input unit indicates the sheet is not cut, the control unit controls the conveying roller so as to return the sheet to the predetermined position without cutting the sheet with the cutter in a case of canceling a print job.
