One trick with the pulsar paper is to re-humidify it. Put it in a
sealed box with a container of water for a few minutes. What I do is
use an inverted Tupperware cake holder (i.e. deep side down) with 1/2
inch of water, then the broiler rack from my toaster oven (1" high),
the paper (glossy side up), then the "bottom" of the cake holder (now
on top).

Rehumidifying gets me a much better toner layer for the transfer.

The rest of the process seems like what I do. I let the laminator
heat up for about 1/2 hr, run the board through 4 times (once in each
direction) then into the water (re-using the cake holder for this).
If the toner doesn't stick, you didn't get it hot enough. If it
transfers properly, you should be able to lightly wipe off the water
with a paper towel, without removing the toner.

A hair dryer will NOT get hot enough to make a difference. They max
out at around 120F, you need to get higher than that to melt toner.
Either use an oven, a heat gun, or the laminator itself to preheat the
board.
