To whom it may concern:
If I remember correct, I was able to follow link from:
to do administrating job by clicking "Adding Printers and Classes" or whatever.
However, unfortunately, what I get today is
Iceweasel can't find the file at /usr/share/doc/cups/online-docs/admin.
So, click "Overview of CUPS" insted, then scroll halfway down, click "Administration" under Where Do I Begin? BINGO, you can proceed.
My penguin is Debian squeeze AMD64.
Hope this helps.
