CUPS problem

[Ashley M. Kirchner]

    This has been driving me batty for a few days now.  I'm running FC5 
with KDE as my desktop.  All updates are current as of this morning.  
Every time I go into Control Center -> Peripherals -> Printers it says 
it's (trying to) initialize the manager then a few seconds later a 
message comes up:

----------
    Unable to retrieve the printer list.  Error message received from 
manager:

    Connection to CUPS server failed.  Check that the CUPS server is 
correctly installed and running.  Error: the IPP request failed for an 
unknown reason.
----------

    Now I searched google for that error and it seems a lot of people 
are having that same problem, and not only on Fedora.  And I couldn't 
find a solution to this either.

    CUPS is running, so I don't quite understand the issue, nor how to 
solve it.  Looking in /var/log/cups/error_log I see this error message:

    E [15/Jul/2006:11:58:37 -0600] CUPS-Get-Printers 
client-error-not-found: No destinations added.

    And in access_log I see this:

    localhost - - [15/Jul/2006:11:58:37 -0600] "POST /printers/ 
HTTP/1.1" 200 112 CUPS-Get-Printers client-error-not-found

    I've been trying to get my Lexmark printer installed but until I can 
solve this problem I can't proceed with anything else.
