Abstract
An inkjet printing apparatus and an inkjet printing method are realized which can improve a print quality while minimizing the volume of waste ink, running cost and throughput degradations. For this purpose, the scan width is set according to the size and position of the print medium and then, based on that scan width, a location where the preliminary ejections are to be executed and the number of times that the preliminary ejection is to be executed in a single preliminary ejection session are determined.
