Best toner transfer paper? Certainly the cheapest!

I had to program some PICs for IR receivers and needed an adapter. I found out the the backing paper from laser labels is ideal from the toner transfer method. It has some sort of wax coating. The laser will print on it OK but the printed parts shouldn't be touched as the toner can smear. Place on clean copper and press down with a hot iron (cotton setting). Don't press too hard as this can cause the toner to smear. Let it cool for 30 seconds then peel off the paper. If you got the pressure and temp right no toner will be left on the backing paper. Even very thin traces are possible. The pads on the adapter for 10Fxxx PICs are only 0.5x0.5mm. The etched adapter is for 16F630 and has 0.65mm pad spacing.

I use a lot of laser labels for Indoor Flyer so the backing paper is really a waste product that I now have a good use for. Forget Press'n'peel - get some laser labels instead.
