Cups clients wont connect

[David Brownlee]

You might try changing "Allow From 10.121.131.255" to "Allow from
10.121.131.0/24".  The Listen directive also is suspicious since you are
trying to bind to the broadcast address.  Change the second Listen to
from "10.121.131.255" to the IP address for lisa.  You might also try
using a fully qualified domain name (lisa.<domain> instead of just lisa).

If you're want to use printer browsing, make sure you are running cupsd
on the clients and that /etc/cups/client.conf has "ServerName
localhost".  In this scenario, printers are configured with cupsd on the
server which broadcasts printers to the network.  cupsd on the clients
see the broadcast an create local print queues automatically.  lpstat on
the client then communicates with cupsd on the client.

Anyway, that's my understanding of the process.

The closest I've found (which describes exactly what I am trying to do) is http://axljab.homelinux.org/Cups_-_Network_Client_Access and I have done what this says to do, but I cannot get my clients to connect to the cups server.
