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.
Is cupsd running?
ps -Af | grep cupsd
service cups start
if it isn't. Also examine
/var/log/cups/error_log
