I work with inkjet printers in research for my Masters program. I found the three blog posts about printing on this blog to be helpful: https://www.kylescholz.com/

The author describes their work to make a very simple DIY inkjet printer for under $1000. While they are using a nozzle that they purchased, you can make a similar one yourself (check out the book "Microdrop generation" by Eric Lee).

All-in-all it's fairly complicated just to start printing droplets, to say nothing of scaling beyond a single nozzle or precisely moving the printhead.

And if you're one of the lucky 10,000 today, Bill Hammack over at the EngineerGuy youtube channel has this[0] fantastic video explaining how piezoelectric microdot printers work.
