This process is known as thermionic and the paper or paper roll involved is known as thermal paper.

Whence the paper passes through the print head of the thermal printer the coated area in contact reacts to the heat and produces an image on the paper sue to the chemical change that takes place. Color print mostly red can also be obtained by using different levels of heat using two colored direct printer. But in the case of receipts and simple images color production is usually not required hence this kind of printer has become very popular all over the globe.

The mechanism of thermal printer comprises of a head which does the printing on paper pushed forward by a platen roller which feeds the paper and springs which provide the right pressure on the thermo sensitive paper to come in contact with the head.

The paper used comprises of a fluoron leuco dye and an acid apart from other chemicals coated upon it. The chemical upon heating by the printer head react with each other to form a color which quickly solidifies on the paper to produce a colored imprint.
