[CentOS] cups sharing ipp

nice instalatin BTW

ok, i activated cupsd sharing and open the port 631 in the security level

when i lpq from withing a network interface i get thi error 
~$ lpq
lpq: error - no default destination available.

and in centos the log shows

i search the archieves and found similar issues but not real response
i tried several things in the config file but no avail
anyone can shed any light why this would be


i am able to print from centos.... its from other pc's in the network that i am not
able

repeat i open port 631:tcp  i also tried udp
and in cups config i specified to share the printer
