I do not know about Ubuntu, but CentOS 4's CUPS system provides a screen for
sharing printers. If you open the machine to anything other than itself, you
can list those other IP addresses that are allowed to use your printer. So
in my case, I allow only the other computer on my LAN to use it. But if I
really trusted you, I could allow your machine to print on my printer too.
