Normally when you print a document, you don't have to worry about who is watching you print. Security agencies and the military however, do. In this video I want to show you what an HP 2225 Ink Jet printer from the early 80's looks like when it has been EMI hardened to TEMPEST standard.
If you would like to see more about the HP ThinkJet 2225, I don't really talk about it here to save on time but Tech Tangents did a wonderful video a few years ago, so you should go check that out - youtube.com/watch?v=gnecsBYWhOI
I've also included a few other links throughout the video to other people's videos on the same printer which you can surprisingly count with one hand.
