Here you are a stupid idea:
what if Zoran will "duplicate" a piezo printing head with only one
nozzle, to use the better
MIS Pro ink? Or another etch-resistant ink.

One reservoir, filled with ink, with a little hole on bottom and a
piezo transducer (buzzer) near that hole,
to act as a pump. Pulse driven.
The ink on the upper side of the piezo will make some pressure to
fill that hole after each spit.
Its inertia will keep the ink the right way.

All on a CNC machine (previously used to drill).
One drop per step, let say.
