QTR-Quadtone RIP

Gday,

I have a Mac Pro (2 x 3ghz Dual Core Intel Xeon, Mac OSC10.5.7) and Epson Stylus Pro 4000 now connected by USB cable.

When I try and print using QuadTone Rip, the printer starts up, checks the paper size, runs the print head over once (no in ejected), then ejects the page and returns to the ready state. So it would seem that Quad Tone is communicating with the printer correctly, but not sending any Image Data. I have been trying to print the Inkseparation.psd and tiff files with no luck. I have tried the old favorites of restarting both the mac and the printer.

Any help glady accepted.

Many thanks

Dom
