Connection refused

[Friedemann Brauer]

I have a printer attached to a computer running xubuntu 7.10 using cups. I configured this for shared printer use, in cupsd.conf , according to the cups documentation:
...
# Allow remote access
Port 631
Listen /var/run/cups/cups.sock
# Share local printers on the local network.
Browsing On
BrowseOrder allow,deny
BrowseAllow all
BrowseAddress @LOCAL
DefaultAuthType Basic
<Location />
  # Allow shared printing...
  Order allow,deny
  Allow all
</Location>
...

When I try to print from a machine that runs RedHat 7.1, I get the error message:
cannot open connection - Connection refused

Are there special directives for cupsd.conf to make this work, or are the two systems just incompatible?

Thanks,
Friedemann
