fry,
I printed one of my files, not big file like Bob's, mine are usually only 25MB or so. It looks just fine from my color laser. I am lucky, I never use hatches or patterns as fills, almost always solids for 2D with image textures for 3D rendering. That seems to work ok as far as I have gone. About you going back to Tiger, I think a sure way would be to back up all your data files on another hard disk and erase your Mac disk and start Tiger with clean install. That should be he worst case. Let's hope VW makes the fixes in VW 12.5 for Leopard instead.
