Actually,
that looks to be like the same firmware as certain intelligent
hubs with integrated Terminal/Printer server capabilities.. I have one
here on my LAN. The model in question is made my a company called
Microplex, and it's a discontinued model called the M208.

There is, however, quite a bit of documentation in the hub's manual about
setting a root password, and the importance of doing so.. don't know who
decided to use this same firmware in plotters/printers or what their
documentation is like, however it seems to come down to the general rule
of never leave a peripheral unpassworded on your network if you want to
avoid these sorts of problems (telnet proxy, etc..)
