If you're looking for accessories for your OKI ML391 Dot Matrix Printer, then you've come to the right place! We've got a wide range of genuine OKI products designed to work perfectly with your office's dot matrix printer, allowing you to get more from your machine without having to fork out on an expensive upgrade.

Get more from your OKI dot matrix printer

Dot matrix printers are true workhorses, and provide no-nonsense, hassle-free printing when bells and whistles are not needed. Our range of accessories will ensure that your OKI printer will keep doing the job, but also enhance its capabilities with a few simple add-ons. Connectivity is massively important for dot matrix devices, as it's likely that these printers will be connected to both legacy machines that use current loop, as well as newer computing devices that use the RS422 standard. Luckily, we stock both types of interface card, as well as the serial interface card, so you can connect your OKI printer to different inputs as required.

OKI for quality

OKI offer great printers for both office and industrial environments, and their range of accessories are built with the same quality materials and practices. This is why we only ever stock genuine OKI products that have come directly from the manufacturer. This means you'll be receiving a product with a full warranty, and one that is easy to install and dispose of in an environmentally friendly way when it reaches the end of its life.

Genuine OKI accessories

Buying new printer accessories will never be a priority for offices with tight IT budgets, and it can be tempting to go for a cheaper alternative to save costs. This can actually be problematic in the long run however, with cheap, low-quality alternatives potentially reducing print quality or even damaging the machine. By only buying genuine OKI products, you'll avoid having to pay twice or call out a printer engineer.
