I was just wondering, and I have not been able to find this on the web, has anyone tried just taking an old printer with piezo head (like and epson apparently according to the inkjet printer wikipedia page) and just loading it with a solution of say sugar or some other more suitable material?
Droplet goes on the surface, water evaporates, leaves deposit. Repeat. Would take a while to print stuff but if you left it going for a couple days (have a way to refill the reservoir) it could be useful.
