OKI B431dn printer

The OKI B431dn is a high-performance monochrome LED printer designed for small-to-medium business environments. It belongs to a specialized category of printers that utilize Light Emitting Diode (LED) technology rather than traditional lasers, a hallmark of OKI's engineering legacy. This specific model is part of a long-standing line of office equipment known for its reliability and fast print speeds.

The brand has its roots in Japan, established in the late 19th century as Meikosha by Kibataro Oki, a pioneer in telecommunications. Over the decades, OKI transitioned from telephones to sophisticated information and communication technology. Manufacturing for OKI printing hardware is distributed globally, with major facilities located in Thailand (OKI Data Manufacturing Thailand) and China, although some specialized components and high-end assembly remain in Japan.

Ownership of the brand remains with OKI Electric Industry Co., Ltd., which is a publicly-traded corporation headquartered in Tokyo, Japan. As of 2026, the company continues to operate as an independent entity, focusing on its 'Medium-Term Business Plan' to enhance social infrastructure and sustainable manufacturing. The brand is managed globally through regional subsidiaries such as OKI Europe Ltd. and OKI Data Americas.
