  • We are looking to purchase an dot matrix printer today for delivery notes - Please advise if the Oki Microline 320 elite is suitable for 3 part NCR paper - size 279 mm h x 241 mm wide. Would it be suitable for windows 7. Would it require a paper holder to cope with the paper feed. Also what is the best way to make the connection to a PC - would it need a serial cable or USB 2.00 cable. I await your response. Regards Sue

    The OKI Microline 320 Elite can handle 5 part (one original + 4 copies) continuous paper which ranges from 76 — 254mm in width. There are drivers available for download from the manufacturers website to enable full compatibility with a windows 7 operating system. As standard, this machine features Paper parking, Low tear-off, Push tractors and single sheet Autoload. But optional accessories can be added such as Pull tractors, cut sheet feeders (Single and Dual) and Roll paper stands. The OKI Microline 320 Elite has a parallel interface only, but this can also be upgraded by adding a Serial Interface if needed. If you require any more information or advice, please give us a call on 0800 840 1992.
