The CUPS config through the web browser works only if CUPS is running
on the local system.

It makes sense for an office workstation, like my machine and my colleagues
machine.

I checked some of my other colleague's systems.  Some run CUPS, some
don't.  All print to the same printer.

I think you missed my point.  I have managed to print without CUPS, only
by circumventing the Gnome desktop.

My colleague can configure his SL5 workstation to print without CUPS,
using KDE.

I gather from this discussion that the SL5 distro Gnome desktop does not
provide a way to configure the system to print directly to a networked
printer *without CUPS*, although the KDE desktop does.

Now, as I said, I was unable to get my system to print using CUPS.
But that is a subject for a different thread.

Cheers, again!
