If the printer responds to an arp request over the wire faster than your
firewall, then its MAC address will be used for the IP addy..
As suggested in another reply, you can manually force a MAC->IP
method, as long as all the machines are on the same subnet..
OR, you can try to 'slow down' the printer's response to ARP
requests... maybe bury it behind a half dozen store-and-forward switches :)
