Abstract of the Disclosure An ink jet copier for copying a master includes an optical scanner which provides an output directly related to the tone of the master at successive points along a scan line on the master. An integator means repetitively integrates the output of the scanner and provides a first enabling print signal each time the integral of the scanner output reaches a predetermined level. The integrator means resets each time this predetermined integral level is reached. A level detector means also monitors the scanner output and provides a second enabling signal when the scanner output exceeds a predetermined level. A print control means is responsive to the level detector means and the integrator means and provides a print control pulse train output upon receipt of either of the first or second enabling signals. An ink jet printer receives the print control means output and deposits selected ink drops along a print line on the copy medium which corresponds to the scan line of the master. -1-
