printing problems

[Krsnendu dasa]

I've tried to set up a printer using cups web interface.
When I try to print a test page I get this error.

"Network host '192.168.0.53' is busy; will retry in 30 seconds..."

I have set up a fixed IP address in dhcpd.conf. It's working.
This is my lts.conf file. Is there anything wrong?
I have rebooted the terminal. Is there anything else I need to do?
