Santa Clara, CA and Kyoto, Japan, March 26, 2025 (GLOBE NEWSWIRE) -- ROHM Semiconductor today announced the new KA2008-B07N70A thermal printhead, compatible with a 2-cell Li-ion battery (7.2V). The product is designed to deliver high print quality with low power consumption and optimized for A4 size printers (210mm width). Height has been reduced by approximately 16% from the conventional 14mm to a best-in-class[1] 11.67mm, contributing to a more compact printer design. Moreover, optimizing the heating element structure while improving the driver IC and wiring layout enables the support for 7.2V operation, reducing the applied energy required for printing by approximately 66% compared to conventional 12V drive (at 50 mm/s print speed). Adjustments to the individual wiring of the resistive elements ensure uniform heat generation, stabilizing print quality and enabling sharp and high-resolution 203dpi printing, even at speeds up to 100 mm/s. In recent years, the thermal printer mar
