Abstract: A printing apparatus includes an encoder that detects the rotation of a driving roller that forms a transport device, an imaging device that images a medium during transport by the transport device, and a controller. In a second detecting unit, the imaging device images the medium irradiated with light that the light emission controller causes the light-emitting unit to emit through a strobe control signal. The second detecting unit acquires movement amount of the medium using a plurality of images with different imaging times at which the medium is imaged. In the first detecting unit, a latching circuit holds a rotation amount of a driving roller totaled by a counter at a timing based on the strobe control signal. The controller controls the discharge timing of the print head based on the rotation amount and the movement amount.
