Mac Printing Problems on a Fiery SI 5750

Kasia Brown, who is having some strange printing problems and asks: "Are there any frequently arising printer problems when having recently installed the OS 8.5 on a G3. I'm finding that the Mac will not allow more than 5 MB of memory to be printed on a fiery si 5750. Frequent replies are "General printer error", "End of File" or "Error 1" when attempting to print documents from Adobe Pagemaker with Graphics." I know there are some Mac folks out there... care to lend a hand?
