Printhead
The printhead is equipped with a series of very small, densely clustered
heating elements (dots) mounted on a ceramic substrate. When electrical
current is supplied to the dots, they get heated rapidly.
Thermal Transfer Print melts the ink on the ribbon. The ink deposits on
the label, and quickly dries after the label leaves the printhead.
In Direct Thermal, the color change of the label is directly caused by the
heating elements without ribbon.
