made no changes to that area in cupsd.conf
OK, and you stated "i am able to print from centos.... its from other pc's in the network that i am not able".
The default settings in cupsd.conf listen on port 631 only from localhost and deny access to the server from anywhere except localhost.
Fix this to allow access from hosts that you are using.
my understanding is the cups-config when specified sharing will add adequates entry. i tried adding Allow 192.168.1.0/24 and no luck any other suggestions should i send you my cupsd.conf file?
