Thermal Printers | Thermal Printer Mechanisms

Compact, reliable low voltage thermal printer mechanisms are the answer for portable printing applications, offering low power consumption to enable long battery life. The innovative small footprint designs free up critical design real estate.

New low voltage LTPD and CAPD series thermal printer mechanisms tackle the challenges of designing smaller, faster, more reliable mobile devices. These new mechanisms deliver exceptional value with dramatic advances in design flexibility, reliability and print performance.

CAPM series direct thermal printer mechanisms are ideal for high performance, heavy-duty embedded printing applications. 300 mm/second print speed means exceptional performance, for a better user experience. Service life ratings of up to 200 km printing and 2 million cuts ensure long-life, trouble-free operation. Extended operating temperature range and thick paper support provide additional application options such as outdoor ticket printing. Units are available in both EZ-OP paper operation and auto-loading designs.


What is Thermal Printing?

Thermal printing involves a heat transferred from a thermal print head to a chemically treated thermal paper. As the heating elements form text and graphics, a thermochemical reaction takes place, so the text and graphics can be seen. Because there are only a few moving parts, thermal printers offer years of reliability, minimal maintenance and consistent operation. One of the most distinctive benefits is its inherently quiet operation.

A thermal printer comprises these key components:


  • Thermal Head: the print head generates heat which causes a thermochemical reaction and prints on the paper
  • Platen: the platen is a rubber roller that feeds paper
  • Spring: the spring applies pressure to the thermal head, keeping it in contact with  the thermosensitive paper


How do Thermal Printer Mechanisms work?

Chemically treated thermal paper is inserted between the thermal head and the platen. The printer sends an electric current to the heating elements of the thermal head, this generates heat. The heating elements used in thermal printers are usually arranged as a line of small closely spaced dots. The heat activates a thermo-sensitive coloring layer of the thermosensitive paper, which changes color where heated.



Thermal printers and thermal print mechanisms are small, light and consume little power, making them ideal for portable and retail applications. Commercial applications of thermal printers include petrol station pump receipts, information kiosks, point-of-sale systems, voucher printers, ticket machines, hospital cardiac monitors and more.
