hello,

does anyone know the temperature required by a thermal print head to
produce a black dot on a piece of thermal paper?

thank you,
david

I would expect its different for each printer and ink formulation.
 
If I remember correct about 150 degrees centrigrade C. I'm sure the ink melt
point is for sure 70-80 oC.

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

You are right. My mistake, I misunderstood thermal transfer ribbon
(sublimation) printer...

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?
