Claim:
1. A printing apparatus comprising: a transport unit that transports a medium; a printing unit that discharges a liquid onto the medium from a print head while the print head moves in a direction intersecting with a transport direction of the medium and performs printing; a corrector that corrects a transport distance of the medium using a correction amount obtained on the basis of the size of a space between a surface of the medium and the print head in the printing unit; a storage unit that stores reference data in which first gap lengths, as sizes of the space between a support that supports the medium and the print head, and thicknesses of media are individually associated with respective items of medium information; and wherein the corrector includes: a space acquiring unit that acquires the size of a space between a surface of the medium and the print head in the printing unit, and a correction amount acquiring unit that corrects the transport distance of the medium using the correction amount obtained on the basis of the size of the space, wherein the space acquiring unit acquires medium information, acquires the first gap length and the thickness of the medium corresponding to the medium information with reference to the reference data on the basis of the medium information, and acquires a second gap length as the size of the space between the surface of the medium and the print head by subtracting the thickness of the medium from the first gap length.
