I think I've got some press and peel somewhere.

The whole idea is as follows (regardless of press & peel or Pulsar...
the difference is how the toner is released).

Clean board.
Print pattern on paper.
run through laminator or iron. Toner becomes soft and adheres to
board, gluing paper to board.

remove paper by either peeling (board to toner is more sticky than
toner to paper)

remove paper by soaking paper (layer of sugar (dextrose) dissolves,
leaving nothing to hold toner to paper).

dry, put on foil if needed, and etch.

What results you get indicate (rather directly) what part doesn't
work.

Variables on toner adhering to board are cleanliness (mostly oils),
non sticky toner (too low temperature), too little pressure (no
adhesion), too much pressure (spreading), too hot (spreading).

You may find a laminator to be more dependable since there are less
variables. Pressure and temperature are more precisely controlled.
