。An ink jet print head with a structure in which the plurality of ejection channel groups in an impulse jet print head are separated into two groups, and the nozzle arrays are arranged in a staggered manner in the vertical direction.
In the head drive circuit, receiving the input first print signal, the first drive circuit drives one of the ejection channel groups.
and a random access drive means for reading and storing the inputted second print signal every time an address is specified.
a memory, a second driving means for driving the other group of ejection channels by a signal read from the random access memory, and a timing pulse generated each time the first print signal is printed. a delay element that delays the timing pulse by a time width of one period or less; a counter that counts the delayed timing pulse and specifies the address of the random access memory; and a delay bit assigned to the output signal of the counter. and a comparator that compares the number signal with the receiver, generates a matching signal, and clears the counter, and print timing is set so that the print patterns from both nozzle groups overlap and match on the paper surface. A drive circuit for an inkjet printer head.
