For a while Parallax was selling a stand alone ink jet
print head. I always wondered if anybody tried it out
on a PCB. I can't find the product on the Parallax
web site anymore, so presumably it is out of production.
I notice that HP has a specialty printer group:

I just wonder if anybody has called them up and asked
them for suggestions for printing on PCB's.
Just a thought. I normally just lurk on the list.
