Oops, foil != thin sheet.
Sorry for the confusion.

Lately I use foto method. I have a cheap Xerox Phaser
3121 (that is in fact made by Samsung). I need to use
2 foils because the toner is not equally distributed on
the tracks. But I have to print at least 4 foils (depending
on the pcb size) to find a pair of them that matches one
each other. Yeah, the foil slips inside the printer but the
opacity is very good with the default toner.

At the PnP the apparent results are very good, but I have
been surprised from time to time with tiny, barely visible
to naked eye, hiccups even on larger tracks.

I also tried foto method on a more expensive one color
Minolta (I do not remember the type). This one prints
precisely the same pcb even on different types of transparent
foil, but it lacks the opacity to produce any kind of tracks
after etching. It may be because it suffered a refill.
