What would cause a printer to flap between an uplinked switch port and a port that's connected to our frame facing router?

this might be a DHCP conflict for an IP address that's already assigned to another host or router. try to reserve the IP address of your router on your DHCP server.

Is the router doing L2TPv3, AToM, or some other l2-over-l3 protocol mechanism? If the MAC address is seen flapping, chances are you are seeing some kind of layer-2 loop, so it would be appropriate to start checking layer-2 connections and protocols such as STP.
