Mac OS X 10.6 Snow Leopard brings a large number of under-the-hood improvements, most of which are not seen by normal users. However, changes to the Print Scan and architecture will affect users of the older printers, scanners, and all-in-one unit. Here are some useful information if you want to do this upgrade.
Apple has bundled printer driver with the latest version of Mac OS X and has taken further steps things in Snow Leopard, this time including software drivers for your multifunction device from Apple, Brother, Canon, Epson, Fuji-Xerox, Gestentner, HP, Infotec, Lanier, Lexmark, NRG, Ricoh, Samsung, Savin, Tektronix, Xerox, and select the driver for some other producers. Check your device against Apple's list to see if compatible for print and / or scanning the Snow Leopard.
A big change in Snow Leopard is the discontinuation of AppleTalk support. AppleTalk, a long-lived protocol for printing and file sharing, saw it’s final iteration in Leopard, and is now completely gone in Mac OS X 10.6 Snow Leopard. If you have a printer that uses AppleTalk, you can try to see if it supports any other methods for printing, such as Bonjour, IP Printing, or generic PCL support. There are some very old printers that support only PCL and AppleTalk, so you can try the generic PCL drivers for those if all other options are unavailable.
