I've used conventional overhead transparencies for laser printers and
photocopiers, the ones I've used were made by Xerox. I have found
that it's important to clean the pcb well, it's best to put it into
FeCl for 10 seconds before ironing. I have to fix some tracks with
Sharpie, too. I think the slowest laser printers are better when
printing on transparencies (or other TTS sheets).
