Abstract
An ink jet recording apparatus having a plurality of recording head units, a test printing operation is carried out to detect the amounts of shift in position of the resultant records, and the amounts of shift thus detected is utilized for determining the maximum number of nozzles to be used and the positions of them for each recording head unit. The number of nozzles to be used is compared with a minimum unit of sheet feed, and determined so that the number of nozzles and the minimum unit are most suitably compatible with each other. In a printing operation, the use of nozzles is controlled, and the amount of feed of the recording sheet is set to the print width which corresponds to the number of nozzles to be used.
