The OKI 590 was one of the most popular 24 pin dot matrix printers that Okidata developed. They are now discontinued but you can still purchase our refurbished 590's. Our printers are ground up refurbs, we tear them down to the frame and each individual part is inspected and replaced when needed. You may also consider the OKI 490 which replaced the 590. We are OKI authorized for sales and service and have 19+ years in the business. We also have available a full selection of ribbons, serial cards, network cards, replacement plastics, and printheads...
