I saw it with my eyes, that the earth may eat.

Someone (I was in a company doing a job) modified an epson printer -
that old 600 ones - to print a circuit board.

The man explained to me: He took an old scanner, and the upper part of
an epson printer. Modified the scanner to "run" the upper part of the
printer thru a table. He diluted pen ink (that pen we use to draw circuits)
and filled the black cartridge with that ink. He said it worked flawlessly,
and show it working to me. JUST AMAZING. So bad he didn't let me take a
photo, since it was "his invention" and he wants to sell it.

I keep saying it IS possible, and I have a canon BJC-something I'll try
to make work this way.

Greetz from Brazil, and keep the faith.
