The Epson Stylus 440 (640?) we had in the family when I was a child was the first time I encountered this piezoelectric effect in technology. Back then you'd get all these paper manuals (or at least we did in India).

I think the little pictures they drew were quite descriptive:

Boy, there was so little content in those days. You didn't have the whole Internet so we used to actually read manuals for entertainment hahaha.

Thank you for your link. That's a sick resin printer from Mimaki. How cool that they started out as a 2D printer company and decided to just layer things up!
