An automatic machine and method for transporting and printing a film track of individual film negatives and corresponding perforated holes, having the film track on a take-up reel and supply reel extending therebetween to a printer, the latter including a light source lens and a screen for printing film on a printing stock, and a bezzle plate having an opening substantially equal in size to that of a negative. A photoelectric device mounted on a yoke for detecting a perforated hole in the film. A control device for stopping the feed of the film track in response to the detection of the perforated hole, and actuating a printer print cycle substantially simultaneously therewith, and subsequently automatically feeding the film track again.
