ABSTRACT:
After the front end area of the print medium has been printed and when the printing is to be continued following the front end area, a preliminary ejection is performed, prior to the current scan, on the nozzles that have not been used in preceding scans but begin to be used in a current scan, in order to remove viscous ink from the nozzles and making them ready to perform ejection. As a result, the ink ejection from the nozzles that begin to be used in the current scan becomes satisfactory.
