A printer has been connected to the router in my office. Windows users can easily discover it, but not for me using Debian. So I used nmap to scan the localhost and found the port 9001 providing a service named `jetdirect` under 192.168.3.113. Then I used cups to set up a network printer manually for me. Bingo! That's the funniest time.
If I use Windows from the very beginning, I would have missed all of the funny things. Treated as a fool, you would be dull:)
