KR2002-Q06N5AA
Thermal print head that achieves high-performance printing with a single Li-ion battery cell
By optimizing the structure of the thermal print head, this product achieves the same printing speed and print image quality as the two-cell drive type while being driven by one cell, and reduces the amount of energy required to apply compared to conventional products. It contributes to the miniaturization and energy saving of thermal printer equipment.It is ideal for battery-powered mobile printer equipment such as logistics labels and payment terminals, which require a small size, light weight, and high service life.

Overview
The KR2002-Q06N5AA utilizes a radically new structure that breaks away from convention. In addition to optimizing the glaze design (which functions as a heat storage layer) and adopting special low resistance heat elements, the protective film structure on the heat elements was optimized. This ensures efficient transfer of generated heat to the print media such as thermal paper and thermal transfer ribbons. At the same time, improvements to the driver IC and wiring structure increase printing performance by efficiently converting power supplied to the device into thermal energy. Simultaneously improving heat transfer and power efficiency allows ROHM to achieve significant energy savings.
These improvements make it possible to achieve the same printing speed and quality as conventional heads driven by two Li-ion battery cells (7.2V) with just a single cell. ROHM also succeeded in reducing the applied energy required for printing by about 30% over existing single-cell drive thermal printheads. This translates to greater energy efficiency while reducing the size and weight of thermal printer equipment.
