データ出力制御回路。A data output control circuit that controls the sending timing of print data sent to the printer in parallel includes a latch circuit that starts sending the print data to the printer upon input of a write signal, and a pulse signal generated by the write signal. a shift register that shifts this pulse signal by multiple stages according to a clock signal and then applies it to the latch circuit as an inhibition signal that prohibits the sending of print data, and the shift register shifts the pulse signal at the timing of the clock signal. A data output control circuit characterized in that a strobe signal is sent to a printer at an intermediate position of a pulse signal shift.
