Enable Access to CUPS Web Interface

To enable access  the CUPS web interface from the network:

Edit the cups configuration file by first running the following command on your server:

vim /etc/cups/cupsd.conf

Find the section that looks like this:

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

Modify it to look like this:

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

Next, find the section that looks like this:

< Location / >
# Restrict access to the server...
Order allow,deny
< /Location >
< Location /admin >
# Restrict access to the admin pages...
Order allow,deny
< /Location >
< Location /admin/conf >
AuthType Default
Require user @SYSTEM
# Restrict access to the configuration files...
Order allow,deny
< /Location >

Modify it to look like this:

< Location / >
# Restrict access to the server...
Order allow,deny
Allow all
< /Location >
< Location /admin >
# Restrict access to the admin pages...
Order allow,deny
Allow all
< /Location >
< Location /admin/conf >
AuthType Default
Require user @SYSTEM
# Restrict access to the configuration files...
Order allow,deny
Allow all
< /Location >

Restart the service:

service cups restart

You should now be able to log into cups on your server with:
http://YOURSERVERIPADDRESS:631/
