Firewall issues
Firewalls restrict data transferred over the network
only to those items specifically approved by the
network administrator. This can have the effect of
making a network connected printer such as the Zebra
P640i unavailable to network users.

The above caveats apply equally to a firewall installed
in a network router, the difference being that such a
firewall affects ALL traffic across it, not just traffic to
and from a lone PC.

If probing fails, you could in theory enter manually
the IP address for the printer in the appropriate driver
setup screen. However, because the IP address is not
known until the printer is configured, this is a Catch
22 situation.
