Failed to print from print server machine!

Hi,
I'm using fedora 8 on i386 linux platform. I'm unable to run local host… but cups is active.
I clicked on ok button but it closed whole application.
What should I do so that I can select the printer and print.
Is by any chance by my network printer isn't configured correctly?
Thanks in advance.

Error
There was a problem connecting to the CUPS server.
