An area on the printing sheet which can be printed through a single scanning operation of a printing head is divided into a plurality of smaller areas. The printing sheet is transported a distance corresponding to each divided area to print the image using different nozzles of the printing head for each divided area. When a back end portion of the printing sheet is printed, the distance transported is reduced to set inoperative nozzles that are not used for the printing operation. Then, when the printing sheet slips out from the upstream roller pair and it is then detected that the printing sheet is to be transported a distance longer than predetermined amount of rotation of the roller, the inoperative nozzles are used to shift an operative nozzle range depending on the extra amount of rotation. Thus, the extra transportation of the printing sheet is corrected.
