Abstract
An ink-jet printing apparatus has a printhead with an array of nozzles and can reduce printing time. The printing elements are divided into plural blocks, each having a predetermined number of nozzles. The blocks to be used for printing are selected based on information to be printed. Blocks from among the selected blocks are designated by a start block designation register and an end block designation register, and a counter is controlled to operate only for the selected blocks to drive the printing elements therein. In this manner, high-speed printing can be performed by avoiding unnecessary discharge control of nozzles not used in printing.
