Run "system-config-printer" on the CUPS server.  When it comes up,
right click on the printer you're trying to share and select
"Sharing..."  Make sure the "This queue is available to other printers"
option is checked, then put in the appropriate "Allowed Hosts" IP stuff.
For example, for my entire firewalled /24 network, I have
"192.168.0.0/255.255.255.0" in there.  Save the changes, then click on
the "Apply" button.

Once the CUPS system restarts, go to one of the clients and also run
system-config-printer.  Click on the "Browsed Queues" thing and you
should see the printer in there.  Select it and you're ready to go.
