Bridging, or something similar

I use an Apple Airport Extreme base station for my home wireless network. I recently came into possesion of an old Linksys WPS54GU2 wireless print server. Unfortunately, the Linksys box will only do WEP, and the Airport Extreme will only do WPA/WPA2. Somewhere in the back of a closet though, I had a Buffalo WHR-G54S wireless router. So I'm wondering if there is some configuration that I can use to get the print server on my network via the Buffalo router? I know I could just hook the Linksys box to the Apple router via an ethernet cable, but the Apple router is not in a good location for me to co-locate the printer. Thanks in advance!
