I use a Powerbook G4 with 512 MB of memory running 10.3.9 - just purchased a new Epson Stylus Photo RX500, and no pdf files will print. I use Acobat Professional 6.0.2. All other files will print perfectly. I have tried reinstalling the software for the printer, I have downloaded the latest driver and installed, have deleted and readded the printer to the printer setup utility and have searched the website for suggestions. I still can't get it to print.

What happens is this: after hit print, the status bar shows printing, but nothing happens.
