What error are you shown (if any)? I sometimes have to re-resend a print job from Parallels to the Mac before the Mac's printer driver kicks off. That means that I start a print job from a Windows app, it doesn't print straight away, and then I start it again from Windows. It usually works the second time around. (Frankly, I haven't tested this in release 9344 as I haven't been near a printer for several weeks now.)
If anyone has problems just download the Bonjour Printer Driver and install it. That solved all my problems.
I am having the same problem. Quickbooks is not able to see my installed printer. All the other XP applications I am running have no problem seeing and talking to the printer, just Quickbooks. Any ideas?
