I don't know anything about setting this up, but this sure looks like a clue:

Code:

# Only listen for connections from the local machine.
Listen localhost:631
Listen /var/run/cups/cups.sock

(from the file you posted)

Here's a snippet from my conf

Code:

# Only listen for connections from the local machine.
Listen localhost:631
Listen 192.168.1.1:631
Listen /var/run/cups/cups.sock

# Show shared printers on the local network.
Browsing On
BrowseOrder allow,deny
# (Change '@LOCAL' to 'ALL' if using directed broadcasts from another subnet.)
BrowseAllow @LOCAL

# Default authentication type, when authentication is required...
DefaultAuthType Basic

# Restrict access to the server...
<Location />
  Order allow,deny
  Allow 192.168.1
</Location>

# Restrict access to the admin pages...
<Location /admin>
  Encryption Required
  Order allow,deny
  Allow 192.168.1
</Location>

# Restrict access to configuration files...
<Location /admin/conf>
  AuthType Basic
  Require user @SYSTEM
  Order allow,deny
  Allow 192.168.1
</Location>

Clearly my network is 192.168.1.xxx

Don't forget to allow traffic on port 631 through your firewall
