TPH technology introduction

A thermal print head (TPH) consists of a heating-element array, driver ICs and a base plate. The controller sends print data to the driver ICs, which switch individual heating dots on and off; the thermal paper coating darkens where heated, forming text and graphics line by line.

Print quality and service life depend on resolution (dpi, i.e. dot density and detail), resistance consistency (density uniformity), wear and impact resistance of the heating elements, and how well the drive timing matches the controller. Kaitong keeps iterating on heating-element structure, film process and resistance tuning, with products covering 203 dpi and 300 dpi across six series from half-inch to 8-inch.
