Interesting!
I imagine using this with an XY table could make up for the lack of resolution. With a conventional inkjet printer, since the location of the head and nozzles are fixed, resolution must make up for lack of placement control of the head.
Drop size might be an issue. However, I imagine you could shoot just about anything out of your single jet.
Is there a UV cure conductive ink, perhaps?
You may require a constant ink feed. I have some pages to flesh out:
