Sheet supplying apparatus and printing apparatus

A method comprising:

• performing printing on a sheet supplied from a roll sheet;
• rotating the roll sheet in a first direction to supply the sheet and a second direction opposite to the first direction;
• detecting the sheet separated from an outer circumference of the roll sheet;
• acquiring a rotational amount of the roll sheet;
• and
• displaying a message in a case in which the sheet separated from the roll sheet rotated in the second direction cannot be detected until an acquired rotation amount reaches a predetermined rotation amount.

A printing apparatus, comprising:

• a printing unit configured to perform printing on a sheet supplied from a roll sheet;
• a driving unit configured to rotate the roll sheet in a first direction to supply the sheet to the printing unit and a second direction opposite to the first direction;
• a detecting unit configured to detect the sheet separated from an outer circumference of the roll sheet;
• an acquiring unit configured to acquire a rotational amount of the roll sheet;
• and
• a control unit configured to control a message to be displayed in a case in which the detecting unit cannot detect the sheet separated from the roll sheet rotated in the second direction until a rotation amount acquired by the acquiring unit reaches a predetermined rotation amount.
