Has anyone heard of this technique?
I'd love to learn more about it. Well, what it is would be a good start!

I have no idea. The only use of inkjet printers that I know of is printing images perhaps and even then you'd need a VERY high quality printer.

As for drawing, presumably you'd need to input something on your computer to be able to generate anything on a printer, as they only respond to information as far as I know.

Do you mean perhaps something similar to those old typewriter 'drawings' where letters and numbers made up an image?

Maybe a bad translation of "airbrushing?"

Just Googled inkjet drawing and foud this.

Does this help you any further?
