Digital BW, The Print

I've run across this problem several times.

First of all, make sure that you are not printing using the highest 2880 dpi setting with OS 
X and Quadtone RIP. It will not will not work. You will see the "printing...." prompt just as 
you described, but nothing will come out of the printer. This is a known issue, I believe.

Otherwise, you should uninstall the software and make sure that there are no backed up 
spool files. (Sorry, I'm not near my computer right now and can't tell you what the path is 
to these files-- try Googling it.)

Also-- Quadtone RIP behaves somewhat erratically if you go into ANY of the other areas in 
the Print Dialog box (such as Manual Feed settings, Scheduled Print, etc.) When I print with 
QTR I make a bee-line straight for the "QuadTone RIP Settings" windoid and click print. I 
know this sounds like voodoo but I think this is a known issue. Perhaps Roy could 
comment further.

Hope this helps.
