Printing to the Internet

You've deployed a brand new networked printer, and after getting it all set up and working, what's the next step?  How about connecting it to the public Internet.  So that anyone, anywhere, at any time can print anything they want and waste all your paper and toner.

Madness you say!  Not it would seem in universities in Taiwan, Korea and Japan.

A little Google hacking and we have 31 internet connected Fuji Xerox printers.  Some of them have public IP addresses, but many of them have been actively published through a NAT firewall.  So this was a conscious choice!

Perhaps it's just a clever way for attackers to exfiltrate data, but I've learned not to attribute to malice that which is better explained by incompetence.

Here's my advice: If you want to print to a work printer from home, this is not the way to do it.
