The other thing is that CUPS listens only to localhost by default. So, I add:
Allow From 192.168.1.*
After each place that cupsd.conf has:
Allow From 127.0.0.1
Again, I normally edit cupsd.conf to make some, but not all, cups admin functions available to users on a lan. The folks on the cups list were very helpful with the admin limit thing.
I'll post .conf examples if anybody needs them.
