WOW!!! These are expensive. This is exactly what I need. I have to find someone who is building this and offering it as a kickstart program (under $5000k). LOL!!!
Small ones (good for a cell phone case or maybe a small tablet) are about $800 on Taobao. Which means you can probably find one on Alibaba for about $1500. 
I remember reading somewhere that the ink can be pretty noxious, and if you are running it indoors, you’d need some sort of air scrubbing system.
