A roll-shaped medium transport device includes: a medium supply unit that keeps a roll body formed by winding a roll-shaped medium on a support shaft, and unwinds and supplies the roll-shaped medium; a transport unit that transports the roll-shaped medium unwound from the roll body; a rotation detecting unit that detects rotation of the support shaft; a rotation unit that rotates the support shaft; and a determination unit that determines abnormality of a transport state of the roll-shaped medium on the basis of the rotation detecting unit when the rotation unit rotates the support shaft, when the rotation detecting unit does not detect the rotation of the support shaft in a state where a transport operation of the roll-shaped medium is performed by the transport unit.
