It's not abundantly hard to bang together something functional, really. It's one of those projects where you just think about the components you have (Camera, Monitor), and then make an enclosure (or find 3d/laser files), then some code that's surely on github to sync them together.
A small printer, though; would turn it from a novelty into something you could e.g. install in a store you owned, and even if you just charged a buck a go it could still be a fun draw.
Got me thinking now what a tiny printing solution like that would/could look like!
EDIT: unsurprisingly, there’s a bunch of iOS/iPadOS solutions. You could theoretically base it off a custom app on an iPad with one of these iThing printers stuffed away and use Square as a POS?
