I have a 5ghz band and a 2.4ghz band broadcasting from my router. Airprint only works if the device (computer, iphone, or ipad) are on the same band.

I don't think this is the case. My L2700DW is right next to the router, so it's connected via Ethernet and isn't on any WiFi network. AirPrint to that printer from my iPhone over WiFi works fine.
