Each toner "recipe" has a specific temperature at which it is plastic
(and sticky) but not liquid. Ideally, you want to heat it to exactly
that temperature, so it sticks to the copper but doesn't deform.
However, that's harder than you'd think. So, each one of us needs to
come up with a pattern of device + temperature + #passes that results in
the toner hitting that "plastic" state. Lower temperature but more
passes? Should work. Higher temperature, fewer passes? Should work.

I always get this, I suspect we just can't tell modern printers to put
down enough toner to make a really thick mask.
