Scanning to email and status updates don't require a server as such, and in the interests of security they generally don't. What I have noted before (despite my brainfart on 9100, excuse me; I was sure I had known it by another name) is that IF the machine is multifunction and can fax, then it would need a smtp server to email to fax. To do this it needs to _receive_ email, not just send. There is usually a driver utility that knows how to speak to it though, but it should be easy to hack. As evidence I checked my printer and it can send email status messages and has no smtp server. Telnet is normal (it is usually secured and used by a qualified technician), and is used to configure other options and nvram settings that may not be available on the menu.
