Epson LQ-310 Dot Matrix Printer


Building on its reputation as the world’s top dot matrix printer maker, Epson has introduced the Epson LQ-310 as the next-generation narrow carriage, 24-pin model that replaces the legendary LQ-300, featuring vastly improved speed and reliability.  


  • Extreme Speed
    • The Epson LQ-310 features a 128KB input data buffer memory that is double that of its predecessor. This enables it to achieve high printing speeds of up to 416 characters per second at 12 CPI – or almost 40% faster than the model it replaces.
  • Improving on Legendary Reliability
    • The Epson LQ-310 also has an improved reliability rating that is an astonishing 67% higher than its predecessor that was already renowned for its dependability. The LQ-310 is rated for a mean time before failure (MTBF) of 10,000 POH (power on hours) compared to the older model’s 6,000 POH.
  • High Impact for Multiple Carbon Copies
    • Achieve optimum efficiency with 4 Part Forms printout (1 Original 3 Copies)
  • Flexible Connectivity
    • With built-in USB, Serial and Parallel Interface options, the LQ-310 is able to connect to just about any output device you need it for.
