摘要： This invention provides a printing head which can prevent an increase in the number of block enable signal lines, and can prevent changes in printing ink density caused by interference due to the relative pressures of nozzles generated in ink discharge, and an image printing apparatus using the printing head. For this purpose, an increase in the number of input signal lines along with an increase in the number of blocks is prevented using a block clock signal or the like instead of a block enable signal as an input signal to the printing head. Three ring counters generate signals having different nozzle driving orders. These signals are selectively used by a ring counter selection signal. Ink is not always discharged from the nozzles in the same output order. This can prevent changes in ink density caused by pressure interference.
