Explanation:
In order to print with a thermal printer, one inserts thermo-sensitive paper between the thermal
head and the platen. The printer sends an electrical current to the heating resistor of the thermal
head, which in turn generates heat in a prescribed pattern. The heat activates the thermo-sensitive
coloring layer of the thermo-sensitive paper, which manifests a pattern of color change in
response.
