dfc: running nmap with "--allports" could make the printer waste a lot of paper, so I won't do it. (FWIW, by pointing my browser to the jetdirect port, I was able to control the timing of the http request with more precision and cancel printing immediately after the first page came out.)
PS. No, I was not trying to replicate what happened -- just trying to get a quick sense of how many ports are open. Sorry for the misunderstanding.
Did you read what I posted? The man page excerpt that I included specifically mentions weird printer behavior.
When you posted the nmap scan report I thought you were trying to replicate what had happened. Otherwise its not really news that print devices have a lot of ports open.
In order to not waste paper you can just have one or two sheets in the tray...
