When a print controller detects a nozzle that is not used for a predetermined period of duration, the print controller rewrites scan data so that the nozzle will be used in a present scan printing operation. The print controller further changes an amount of sheet feed in association with the rewritten scan data. Then, the present scan printing operation is performed. It is therefore possible to prevent any nozzles from not being used continuously for the predetermined period of time.
