A method of controlling transport amounts of a pair of first rollers and a pair of second rollers, the pair of first rollers operable to nip a medium so as to transport the medium in a transport direction, the pair of second rollers operable to nip the medium so as to transport the medium and disposed at a downstream side of the pair of first rollers in the transport direction, the medium on which a recording is performed by a recording head disposed between the pair of first rollers and the pair of second rollers, the method includes performing a first correction with respect to the transport amounts of the pair of first rollers and the pair of second rollers; and performing a second correction with respect to the transport amounts of at least the pair of first rollers, from a state in which length between a trailing end of the medium and a nip point of the medium at which the medium is nipped by the pair of first rollers is a predetermined length to a state in which the medium is released from being nipped by the pair of first rollers.
