Frequently Asked Questions

What makes the OKI Pro Series different from standard laser printers?

The Pro Series uses high-definition digital LED technology specifically designed for commercial print applications. Unlike standard office printers, they offer unique capabilities such as five-colour printing (adding white or clear gloss), support for exceptionally heavy media up to 360gsm, and the ability to print on difficult substrates like dark card or clear vinyl.

Can I print my own labels with the OKI Pro Series?

Yes, the OKI Pro1050 is specifically designed for short-run, professional label printing. It enables you to print on a wide range of label rolls in full CMYK plus white, meaning you can produce waterproof and durable labels for packaging, bottles, and chemical containers on demand.

Do OKI Pro printers offer five-colour printing?

Yes, several models in the Pro Series feature five-colour printing. The OKI Pro9541 can print CMYK + White or Clear Gloss, the OKI Pro9542 prints CMYK with a dominant white underlay, and the OKI Pro1050 label printer uses CMYK + White.

Are the running costs scalable for commercial use?

The OKI Pro Series is designed with commercial print users in mind, offering high-capacity toner cartridges and imaging drums that deliver a highly competitive cost-per-page for short and medium print runs.

Where can I buy genuine consumables for my OKI Pro printer?

We stock the complete range of original OKI toner cartridges, image drums, transfer belts, and fuser units for every OKI Pro Series printer, ready for next-day dispatch from our UK warehouse.
