QTR-Quadtone RIP

I got no response from this last post so I will try again:

I am trying to get QTR to see my Epson 10000. I
have it both connected via USB and network. If I run the Epson
utility from within Printer Setup Utility in OSX it sees it fine,
both via USB and network, and even provides status of ink remaining.
But if in Photoshop I set up everything correctly and ready to print,
it appears to rip it, but will not send the data to the printer. If I
just print to preview it looks fine and again if I hit the print
button from there I see the status bar saying it is printing and then
within seconds it clears and no data is sent to the printer. There
must be some simple thing I am overlooking.

Thanks,
Mark
