Looks like a slightly larger version of the Pentax PocketJet200 I got decades ago and still have in storage somewhere. It's even smaller than this and has a removable rechargeable battery. I think they were used in cop cars and delivery vehicles. It understood a subset of PCL which made it super easy to generate output without needing any special driver. I used it a few times and never used it again because it's super neat and super useless for most needs. I got it because it turned me on to have a printer in my laptop bag. But the images fade and the paper is annoying to use, source, handle, everything. And this was all decades ago and it was even smaller than this thing while using the same full size paper. I like the chrome S bar roll holder though.
