My daughter will be taking her new MacBook unibody to college. I'd like to provide her a setup that's as wireless as possible--backup drive, printer, and speakers. For backup, I plan to get her an Airport Extreme base station and attach an external hard drive by USB. Could the MacBook connect to the AEBS and a WiFi printer (like the HP Office Jet Pro 8000) at the same time? Would the have to be on different bands--say, B or G for the printer, N for the Airport Extreme?
