Comment:
I'd add that while KDE won't let me add a printer or use one, gnome-
cups-manager worked fine, and I can print without a problem using gnome
apps or lp in a console.

There is absolutely no problem with he cups server. It starts well and
there's no error in /var/log/cups/error_log.

However, /var/log/cups/access_log have entries like :
localhost - - [01/Mar/2006:16:43:44 +0100] "POST /admin/ HTTP/1.1" 200 358 CUPS-Add-Printer client-error-bad-request
