Funny. I install MANY printers on macs that NEED to download drivers. Please do not toss about poor info. Sure mac may have BASIC drivers but if you want to use half the features a printer comes with, You will have at least a 50% chance of having to download drivers. Granted, this is with HP printers.
All mac does is use the CUPS printing system, same as unix and linux.
What it comes down to is wether or not you know how to use a computer. Of course macs have been meant for those who lack pc skills. If you think I am being an ass, read up on it. Apple has used that in the past as a selling point.
Also remember, apple is MORE likely to stop supporting your printer than windows. Apple is famous for NOT supporting legacy hardware. Vista will still support most legacy equipment back to 2000.
Main thing is just cause it is apple does not mean it automatically works and anyone who says so is lying. Bottom line.

Sorry have to be the one to tell the truth.
