hello everyone -- i've successfully setup my Brother 7820n with my airport express for printing through my USB port on the Airport Express, but haven't been able to figure out the scanning i've seen where people have successfully done it, but nobody has explained HOW . . . just wanted to figure this out. right now printing is perfect, just wondering if i should be using the ethernet port on the Airport Express for scanning and printing? any help would be appreciated! also, how does one update the firmware on a printer if it's in another room on the Airport Express?
