Music notation typewriter?

Is this real? 

Does it count as an "instrument?"  Haha.

That would be amazing if it was real but… I don't think so.

Possibly real, but of very limited utility.  Getting the note in the right place peering through that black ribbon would be very difficult.  A box of rubber stamps would be more useful.
All totally obsolete once the dot matrix printer became affordable with PC software to drive it, about 1985?

Well I'll be damned. I guess I was wrong;

Interesting, but yeah... I think writing it out by hand could be cleaner and faster.  The beams, is what I keep thinking.  You could leave them off with this thing and do all quarter notes, or mostly, and then come back later and draw in the beams.

It's tedious but it's not too hard to learn to write out by hand nearly as clean as print.  You can do it in pencil, possibly larger than normal and than shrink it, and then copy it on a xerox machine to moosh everything a bit.  It can come out looking pretty close to print.   Yes, I'm serious.
