We use a HP DesignJet ColorPro GA under OSX on a Mac G4 using Adobe PressReady. We have installed OS 9 as Mac Classic Environment to be able to run Photoshop 6, Illustrator 9 and more older software.
Recently we purchased Adobe CS and there have been problems printing.

Now the printer can't be found by any of the Adobe CS packages while it still works under the older versions. We think we need a new version of Adobe PressReady but we haven't found a version that'll run under OS X.

Any suggestions? I've looked through the topics but couldn't find anything related. Adobe CS does recognize the HP LaserJet 4100 printers, but not this one.

Thanks in advance.
