Hi Gene,
Are the printers connected to the lan directly (as via wired or 
wireless) connection?
if not, then I do not think that you should use ipp protocol.
Instead you need to use samba. Printer configuration lets you select 
samba as
the protocol. However, the machines to which the printers are directly 
need to configure samba correctly and share those printers properly. If 
they are
windows machines, then they too should share the printer resource.
On the clients that need to print to those machines, you use printer 
config tool
from the administration menu (system->administration->printers) and be sure
that when you add the printer, you select "Windows printer via SAMBA",
and take it from there.
Be sure that the firewall (if it is enabled) on the machines to which 
the printers
are connected, allows traffic from the client machines.

Good luck,
