Abstract

PURPOSE:To compensate intervals of head with inexpensive constitution by delaying a read of memory for two ink jet heads by a prescribed dot unit on the basis of a print region signal. CONSTITUTION:Synchronizing crcuit 21, when a print signal is supplied from print region signal generating circuit 20, makes charge pulses into a clock signal, which is supplied to D-FF to generate a signal synchronizing with the rise and fall of D-FF. This signal is sent as a clear signal to counter 24, which is cleared. At this time, D-FF and the charge pulses are ANDed by AND gate circuit 22 to read print information out of red-color memory 23 and charge control circuir 17 is controlled to print data in red. Counter 24 counts the charge pulses and, when counting up to a prescribed number, makes comparing circuit 25 outputs a coincidence signal, with which the output signal of D-FF is sampled. As a result, black-color memory 28 is read with a time lag of a prescribed number of dots behind the red-color signal.
