I kind of agree that unless you do large file transfers or media streaming, 802.11b is probably sufficient.

However, I don't think too many 802.11b APs had the strong encryption protocols. I have a 802.11g AP which has WPA and I am thinking about getting a new one to get WPA2. I don't really do anything super secret (i.e. online banking) over wireless at home because of security concerns. Also, the AP is potentially a weak link in your home network's security.

On the print server, it might be better to get one that's Ethernet on one side and USB (or whatever your printer's interface is) and just attach to your router (most APs are also routers).
