I've measured melting points for two toners, the original
toner in my HP LaserJet 6L, and the eBay toner I used to
refill my Samsung ML-1710.
They don't abruptly transition from solid to liquid, but
become soft and waxy, then sticky, then gooey, so "melting
point" needs clarification.
The HP toner could be smeared with a hot iron at 103+/-3
deg. C. The refill toner smeared at 99+/-2 deg. C.
There's a decorative metallic transfer film you can iron
on to laser-printed text. I measured the temperatures needed
to transfer: 110 +/- 3 deg C for the HP, and 81 +/- 3 deg C
for the refill stuff.

The refill toner I used was from TonerKits on eBay--
cheap, great service. I just poured it in & prints as
well or better on paper than the original. No differences
for toner transfer noticed.

I've no idea how suitable it is, but I have 1,4Kg of
Toshiba T-6560 toner!
