What Is a TPH That Supports Printer Output? Understanding Thermal Print Heads from the Basics

What Is a TPH (Thermal Print Head)?

A TPH (Thermal Print Head) is a printer device that forms images by selectively generating heat. Electrical current is applied to precisely arranged resistive elements on a substrate, heating only the required areas. This heat is then transferred to print media such as thermal paper or thermal transfer ink ribbons to produce images.
TPHs are widely used in a broad range of applications, including photo printers, label printers, card printers, and medical dry imagers.
Toshiba Hokuto Electronic manufactures TPHs designed for diverse applications and is recognized as one of the world’s leading manufacturers.
The company offers an extensive lineup with recording widths ranging from 50 to 680 mm and resolutions from 200 to 1200 dpi.
Dpi (dots per inch) is a unit of resolution that indicates the number of resistive elements arranged per inch (25.4 mm).

Applications of Thermal Print Heads

Our lineup covers recording widths up to long-format A0 size and offers ultra-high-resolution models with up to 1200 dpi.
With an industry-leading resolution of 1200 dpi, our Thermal Print Heads set thebenchmark for performance and quality.
