Hi all,
I am trying to install printer on my FC7. when i start
the settings-->printer a message pop up:
Unable to retrive the printer list. error message
recieved from manager. connection to cups server
failed. Check that cups server is correctly installed
& running. Error: the IPP request failed fo an unknown
reason.

How to correct it.
