Abstract
The invention is a transport method that transports a medium by causing a transport roller to rotate based on a corrected target transport amount, after correcting the target transport amount that is targeted based on a correction value and includes: printing a first pattern on a medium, printing a second pattern after the medium has been transported by causing the transport roller to rotate by a rotation amount of less than one rotation from a rotation position of the transport roller at a time of printing the first pattern, printing a third pattern after the medium has been transported by causing the transport roller to rotate by a rotation amount of one rotation from a rotation position of the transport roller at a time of printing the first pattern, printing a fourth pattern after the medium has been transported by causing the transport roller to rotate by a rotation amount of one rotation from a rotation position of the transport roller at a time of printing the second pattern, calculating a first correction value based on the first pattern and the third pattern, calculating a second correction value based on the second pattern and the fourth pattern, transporting the medium by correcting the target transport amount based on the first correction value or the second correction value depending on the relative position of the medium with respect to the transport roller.
