Printing apparatus and control method for printing apparatus

A printing apparatus, comprising:

• a support member configured to support a core body of a roll medium formed by winding a print medium around the core body in a roll shape;
• a transport mechanism configured to transport the elongated print medium drawn out from the roll medium along a transport path;
• a first accommodation sidewall and a second accommodation sidewall that constitute a part of an accommodation section configured to accommodate the roll medium, the first accommodation sidewall and the second accommodation sidewall being disposed to face each other in a width direction that intersects a transport direction of the print medium, the first accommodation side having a groove, the roll medium being accommodated in the accommodation section by the support member engaged with the groove;
• a print head configured to print an image on the print medium;
• a trailing edge detection section configured to detect that all of the print medium that is drawable out from the roll medium has been drawn out by the transport mechanism by detecting that the support member separated from the engagement surface of the groove, the trailing edge detection section comprising a lever that, in a state in which the support member is engaged with the engagement surface, contacts the support member and a biasing member that biases the lever toward the support member, wherein only when the support member separates from the engagement surface, the lever is displaced by the biasing force of the biasing member;
• and
• a medium detection section configured to detect presence or absence of the print medium in the transport path, wherein even when the trailing edge detection section does not detect that the support member separated from the engagement surface, the control section determines that all of the print medium that is drawable out from the roll medium has been drawn out by the transport mechanism when the medium detection section detects that there is no print medium.
