Some printers allow remote telnet control (Xerox, mainly, running Solaris
8 I think), and all of those come with root password left blank.
An attacker can then install sniffers and whatnot on the printer, which
happily runs on with practically no slowdown.
Also, network connected fax machines can be used to send faxes from
remote locations, and guess who gets to pay the bill...
Check your printers/faxes manuals to see if they are susceptible.
