The Epson LX-310 also has an improved reliability rating that is an astonishing 67% higher than its predecessor that was already renowned for its dependability. This enables it to achieve high printing speeds of up to 357 characters per second at 12 CPI. The Epson LX-310 features a 128KB input data buffer memory that is double that of its predecessor. Building on its reputation as the world’s top dot matrix printer maker, Epson has introduced the Epson LX-310 as the next-generation narrow carriage, 9-pin model that replaces the legendary LX-300, featuring vastly improved speed and reliability.
