Can the HP plotter correctly position a copper clad board?  I did not

How much can you find this plotter for now?  I assume they don't make it
anymore.  I would think with a little more effort the ink of a regular
HP plotter pen could be replaced with the ink of the pen you had described.
This would allow the use of just about any plotter.  You may even be able 
to machine your own pens out of rod aluminum stock!
