No, the printer only has an IP address if it's a standalone network

connected as one. Cups will be listening (by default) on port 631, on
the computer's IP address. I can't remember if it listens to anything
other than localhost by default, you may need to change the cupsd
configuration file to allow connections from other machines. Check
with netstat. If you have Windows machines in your network, then Samba
is probably the best way to share the printer. Since I do that, I
can't comment on the direct use of Cups over the network. My
workstation has cupsd listening on all interfaces UDP, but only
localhost TCP. I would assume that is the default, since there's never
been a printer attached to this machine.
With Windows Vista/7, it's pretty straightforward to add the CUPS URL
for the printer directly as a networked printer. It should also work
under XP, but it's been a while since I've had to deal with XP and
networked printers. Samba would basically make the printer show up on
browse.
It's as simple as setting up a network printer under Vista/7 and
entering "http://<address of sharing
machine>:631/printers/print_queue_name" as the printer destination.
