Abstract
A printing device and a positioning method of a printing device can accurately compensate for deviation between the intended conveyance of the print medium and the actual movement of the print medium when conveyed. A printer 5 has a conveyance motor 32 that can selectively convey print media forward and reverse; and a control unit 101 controls the conveyance motor 32 to convey the print medium. The control unit 101 executes a specific sequence, and calculates the difference in the conveyance amount of the print medium in each direction when the conveyance unit is operated the same amount in both directions. This sequence includes changing from forward to reverse and from reverse to forward the same number of times, a first conveyance of the continuous paper M forward or reverse, and a second conveyance in the opposite direction as the first conveyance.
