What printer [tested] for FreeRadius + WPA (EAP/TLS) WLAN network?

Hello, I use FreeRadius with WPA (EAP/TLS) in my wireless network. Recently I was asked to select and buy wireless printer (with wireless print server built-in). And here is a problem: Does anybody know what printer supports WPA with EAP/TLS? I'm talking about models tested in WPA EAP/TLS-enabled WLAN network (we have HP DeskJet 5850 but it doesn't work - it's theoretically WPA-compatible, I can install certificates but it doesn't log to network, In WEP-only environment it works great).
