Claim:
A method comprising: conveying, on a conveyer, a pallet having a print substrate thereon; stopping the pallet at a first holding position; holding the pallet, stopped at the first holding position, to be spaced apart from the conveyer; conducting a processing operation for printing on the print substrate on the pallet when the pallet is spaced apart from the conveyer; stopping a second pallet at a second holding position; and holding the second pallet, stopped at the second holding position, to be spaced apart from the conveyer, wherein the second holding position is upstream of the first holding position in the pallet conveying direction, while the processing operation is conducted on a first print substrate on a first pallet held at the first position, the second pallet on which an unprocessed second print substrate is placed and which is stopped at the second holding position is then held to be spaced apart from the conveyer for waiting, and after the processing operation, the first pallet is returned onto the conveyer so that the first pallet is conveyed again and the second pallet is returned onto the conveyer and is conveyed to the first holding position.
