I own a G4 powerbook running OS X 10.3.5, 1.5 GHz, 256 MB RAM and recently bought a HP deskjet 9800 that I was told was mac compatible. The adobe programs I use create postscripted images but the 9800 is a non-postscripted printer. The graphics I print on this printer are a poor quality because of this. Can I install a driver in my printer so that it will print properly? Are there any other options other than buying a new printer?
