ABSTRACT:
A printing apparatus and a print control method can obtain excellent ink discharge without reducing the life of a printhead for image formation using plural sizes of ink droplets. Unop printing by discharging ink from an ink-jet printhead, having plural printing elements capable of discharging ink droplets in plural sizes, to a print medium, the number of concurrently-driven printing elements is counted corresponding to each respective size of the plural sizes, based on input print data, then a drive pulse applied to the concurrently-driven printing elements corresponding to the respective size of the plural sizes is determined based ont he result of counting, and the drive pulse is applied to the concurrently-driven printing elements.
