Queue Configuration

You can use above tools to share or setup a printer. The default configuration file is /etc/cups/cupsd.conf. You can edit this file to allow network access:
# vi /etc/cups/cupsd.conf

Modified text:
<Location/>
Order Deny,Allow
Deny From All
Allow From 127.0.0.1
Allow From 192.168.1.*
</Location>

CUPS will accept connection from localhost and network 192.168.1.0/24. Just restart the service and your printer queue is ready to accept connections from clients:
# /etc/init.d/cups restart

Open Iptables 631 port
