Abstract: A printing device includes a printing unit, a pair of transporting rollers (a pair of rollers) that is disposed right before the printing unit and that transport a medium to the printing unit, and a transportation direction changing mechanism that is disposed on an upstream side of the pair of transporting rollers and that changes a transportation direction of the medium before the medium is nipped by the pair of transporting rollers. The transportation direction changing mechanism changes a transportation direction of a following medium such that a leading end portion of the following medium overlaps a preceding medium when the printing unit performs printing in a state where the preceding medium is nipped by the pair of transporting rollers.
