connection to cups server failed only if from server itself in KDE applications

I am having a problem with kprinter not being able to access cups printing when printing from the server itself using a KDE application. I use Fedora Core 3.

When I start kprinter, and CUPS is chosen as printing system, and it is from the server itself, then an error message

Connection to CUPS server failed.
Check that the CUPS server is correctly installed and running.
Error: host not found


I can see and print from the server to any of the printers if I choose LPRng system option.
I can see and print in KDE applications from anywhere EXCEPT from the server, using CUPS option.
I can see and print in non-KDE applications from anywhere using CUPS option, whether from the server or elsewhere.

So I can only deduce it's not the CUPS setup, but kprinter/KDE not properly accessing cups server if running from the same machine as the CUPS server.

I have /etc/cups/cupsd.conf with the following options (I am very sure none of other options
are relevant here):

Browsing On
BrowseProtocols cups
BrowseOrder Deny,Allow
BrowseAllow from
BrowseAllow from

Anyone see any problem and how to fix this weird KDE printing problem if running from the same machine as the CUPS server?

It is quite annoying to run kprinter everytime when I switch between server and non-server desktop.
And yes, I DO NEED to use the server as a desktop workstation.
