1. A printing apparatus comprising:
a driving unit configured to cause a roll sheet to rotate in a first direction and a second direction opposite to the first direction;
a printing unit configured to perform printing on a sheet supplied from the roll sheet being rotated in the first direction by the driving unit;
a detecting unit configured to detect a sheet of the roll sheet; and
a rotation amount sensor configured to acquire a rotation amount of the roll sheet,
wherein in a case in which the sheet is not detected by the detecting unit and the roation amount acquired by the rotation amount sensor exceeds a predetermined value, the driving unit stops the rotation of the roll sheet.
