We discovered that our HP Officejet 6700 was directly accessible from the internet after someone printed a pamphlet about 'Serpent People in New York' (quite hilarious actually).
Ofcourse, we'd like to prevent this from happening again. However, I quite like the 'printing from the internet'-feature (so that I can print stuff when away from home).
Is it possible to somehow add some protection to printing? E.g. a password that each computer should have, a SSL-certificate I have to install, ... ?
I have a few Windows machines and one linux machine that will print regularly to this machine from the local network, and one linux machine that will most often print via the internet.
