Generally, you'd do that with CUPS (or with HPLIP if it's a Hewlett-Packard printer; HPLIP does the CUPS set up for you). If you don't have an H-P printer, you'll need the appropriate printer description files that came with the printer (not the Windows stuff, the PPD files).
Network printers are best done using a fixed-IP address rather than DHCP; this will work fine if you address the printer below the first address DHCP hands out. DHCP addresses generally start at 100, you can safely use a lower address as fixed-IP; e.g., 192.168.1.10, 192.168.1.20 and so on. Make an entry in /etc/hosts
for the printer something like this
then you can refer to the printer by that name (InkJet). Your intranet addresses may vary, of course, but that's the idea.
Hope this helps some.
