I would expect its different for each printer and ink formulation.

Thermal printers do not use ink. The paper (same as thermal fax paper)
reacts to heat.

Fairy nuff, I wasn't thinking about fax machines but different
technologies to fire ink at a piece of paper.

In which case the answer is actually quite low I think, after all when
the paper comes out it doesnt feel hot. When you use pressure on the
paper to generate the black is that heat from friction or just the
pressure?
