In article <308@serene.UUCP> gbell@pnet12.cts.com (Greg Bell) suggest
an ingenious way to fabricate short runs of PCB. He uses a copying
machine to transfer the artwork onto an OHP transparency, then irons it
onto the PC board. The transfered copier toner acts as an etch-resist.

A suggestion:
   Use a laser printer to generate transparencies. This works great
   with Apple LaserWriters(tm). MAKE SURE YOU USE COPIER-SAFE MATERIAL.

And a query:
   Using manual feed, NEC machines can print on rather thick material.
   Will they print directly on thin PCB? Unfortunately* I have no access
   to one; otherwise I'd try it on thin material and smooth the edges to
   save the printer drum from scratches. Has anybody tried this?

* My bad luck may have just saved a $3k printer...
