There used to be people on eBay that sold plans to turn various printer
models into CD printers, presumably by allowing them to pass the thicker
material through the machine. I don't know if these people are still
around, but it might be worth a shot, or at least, a google search about
home made CD printers. I think the only way to get a small size PCB to
pass reliably is with some sort of carrier. If the carrier was cheap
enough, then it could easily be remade for each new PCB size. Cardboard
of some sort springs to mind, though I suppose it might wear after a
while. As a side thought, if you did use cardboard, perhaps you could
use little spikey wheels along the edges to move it along. Something
like tractor feed on a dot matrix printer, but without preformed holes.
Since the carrier would be basically garbage anyways, who cares what it
looks like after?

I hope you come up with something useful in regards to the ink and then
share :) The gun bluing sounds interesting, will it work with regular
print heads though? I'd love a machine that could print directly onto
PCBs. Part of the reason I hand wire all my projects is it's just easier
(in my current situation) than doing a PCB. Of course, the other reason
is that I don't know how to design PCBs :) I did download Eagle
yesterday though, and I will likely try it eventually. Figures the
project I want to use it on will need a bigger board that I can do with
the freeware version.
