Telnet is an application layer protocol used on the Internet. So the first thing to do is to find a printer that 'speaks' the telnet-protocol as defined in https://tools.ietf.org/html/rfc854. I don't thnik those exist.

I would like to send a print command from a server hosted in Amazon, to a printer installed in a different location, using telnet.
1) is that possible?
2) what kind of router-modem 3g, RG45 do I need? any reccomendation?
Thanks
