Claim Text:
1. A printing apparatus configured and arranged to perform printing by discharging fluid from a printing head onto a printing medium having a lens sheet in which a plurality of lens bodies are disposed in parallel, the printing apparatus comprising: a control unit configured to control a fluid discharge, the printing medium having a first end portion and a second end portion, with one of the lens bodies being disposed on the first end portion and another of the lens bodies being disposed on the second end portion, a part of the another of the lens bodies disposed on the second end portion being cut out compared to a shape of the one of the lens bodies disposed on the first end portion, a printing head movement unit configured and arranged to reciprocate the printing head in a main scanning direction, an end portion detection unit configured and arranged to detect the first end portion of the printing medium in the main scanning direction, a transport unit configured and arranged to transport the printing medium to a fluid discharge region in which the printing head is able to discharge the fluid, the control unit controlling the fluid discharge so that the fluid is discharged onto the first end portion as a discharge start position, the control unit controlling the printing head and the printing head movement unit such that the control unit discharges the fluid onto the first end portion of the printing medium which is detected by the end portion detection unit as the discharge start position, the control unit controlling the printing head and the printing head movement unit such that the printing head moves while discharging the fluid when the printing head moves from the first end portion to the second end portion, and controlling the printing head and the printing head movement unit such that the printing head moves without discharging the fluid when the printing head moves from the second end portion to the first end portion, a movement velocity of the printing head when the printing head moves without discharging the fluid being faster than a movement velocity of the printing head when the printing head moves while discharging the fluid, and the control unit controlling the printing head movement unit, the end portion detection unit, and the transport unit such that the printing medium is transported by a predetermined amount and then the first end portion is detected by the end portion detection unit while the printing head moves from the second end portion to the first end portion, and controlling the printing head and the printing head movement unit such that a position of the first end portion is estimated on the basis of a transport amount according to the transport unit when the first end portion is not able to be detected by the end portion detection unit, and the fluid discharge is started from the estimated position of the first end portion.
