I wish printers could have a mode like this to print random images from an album, or a calendar, rather than wastefully draining ink into a sponge every few days.

If nothing else, maybe it could be some kid's high school science fair project idea.

How about printing a QR code for a randomly generated private key for Satoshi Nakamoto's Bitcoin wallet, then every few days you get a tiny moment of excitement, hope, and then disappointment. It's still wasteful, but it could pay off big time?

Or if you have a printer/scanner combo, you can turn it into a pen pal!

this is an amazing youtube video idea if you could get a type writer to do it.

		Maybe I'm misremembering, but I'm sure there was something on HN a few weeks ago about an electric typewriter that someone had connected to (I'm guessing) a Raspberry Pi? My search-fu is currently failing to find anything particularly recently, at the moment.
