"Electronics Now" ran an article about a decade ago explaining how
to do this with copper flex material, so it does appear to work.
The nicest thing is that the toner is a good etchant resist. I've
not heard of anyone accomplishing this with rigid boards though.
Back when I worked at HP, several of us tried to put together a
system using an inkjet printer and waterproof inks. In the end it
was just cheaper and easier to use PCB Express, and the idea got
dropped.

Getting into old tech where neither a working printer, nor a driver
to run it, are all that easy to come by:

Flat bed pen plotters.

Type 1, the "paper lays there and the printhead does all the moving"
type. Obviously easy.

Type 2, a particular flavor of HP, I'll remember the number wrong, no
doubt, perhaps a 7550? It moved the paper for one axis and the head
for the other axis, but the paper path was flat, so a rigid material
(such as a board) could be plotted.

In either case, a resist-ink pen got the job done.

These days directly cutting the board using a CNC router may be as
easy, it's dry, and it gets the job done in a single step. Noisy and
messy, though.


HP 7475A, I still have one, it does print boards nicely, though I had
to make a frame to hold smaller boards.

I have seen them. A generic HPGL driver should do. What interface
though, GPIB is getting rare now.


It uses a serial interface.
