If you run a garage, car dealership, motor factors business or any trade that supplies registered vehicles, professional number plate printing is likely something you have already considered. The ability to print compliant, durable and high quality plates in house is a genuine commercial advantage — cutting waiting times, reducing supplier costs and giving you full control over output quality.

This guide covers everything you need to know about reg plate printing in the UK, from legal requirements and equipment options to the OKI systems that garages and trade users trust most.

What Are the Legal Requirements for Number Plate Printing in the UK?

Before investing in a number plate printer, it is essential to understand the regulatory landscape. In the UK, number plates must conform to the British Standard BS AU 145e and can only be supplied by Registered Number Plate Suppliers (RNPS), who are authorised by the DVLA.

Key requirements include:

• Plates must display characters in the mandatory Charles Wright 2001 font
• Background colours must meet reflectivity standards (white front, yellow rear)
• The supplier’s name, postcode and British Standard mark must be printed on the plate
• You must sight and record customer identity and vehicle documents before supply

Registering as an RNPS is straightforward and allows you to legally supply and print number plates on a commercial basis. Once registered, having your own number plate printing system makes the whole process significantly more efficient.

Why Print Number Plates In-House?

Many garages start out ordering plates from an external supplier. That works fine at low volumes, but as your business grows the costs, delays and logistics of third party supply quickly become a frustration. In-house licence plate printing gives you:

• Speed — plates printed on demand rather than waiting for delivery
• Cost savings — print cost per plate drops significantly at volume
• Quality control — you oversee every plate that leaves your premises
• Revenue — the ability to supply plates to other traders and the public as an RNPS

What Equipment Do You Need for Number Plate Printing?

A professional number plate printing system typically comprises three components working together: a printer, specialist software, and the correct plate blanks and consumables.

The Printer

The OKI range is widely regarded as the industry standard for number plate production in the UK. OKI LED printers deliver sharp, durable output on reflective and non-reflective plate materials, and their toner-based printing technology ensures the finished plate is resistant to weather, UV and general wear.

The two most popular models used for car number plate printing are:

• OKI B433dn — a robust mono LED printer well suited to producing the black text layer on standard reflective blanks
• OKI Pro 9542 — the five-colour A3 printer that adds a white opaque layer, enabling printing on yellow reflective material and delivering an exceptionally clean, compliant finish

You can explore both models in detail on the OKI Supplies Number Plate Printer page.

The Software

Dedicated number plate software handles layout, font compliance, supplier details and the BS mark automatically, making it easy to produce correctly formatted plates every time. Most systems integrate directly with the OKI printer range.

Plate Blanks and Consumables

You will need compliant reflective plate blanks, typically available in standard sizes (standard oblong, short, motorcycle). OKI genuine toners ensure consistent print quality and longevity.

Choosing the Right Number Plate Printer for Your Business

The right registration plate printer depends on your expected volumes and the types of plates you need to produce.

Low to Medium Volume: OKI B433dn

For garages printing primarily standard mono plates at moderate volumes, the OKI B433dn is an excellent, cost-effective starting point. Its compact footprint suits a busy workshop environment and OKI’s LED print technology means reliable output with minimal maintenance.

Higher Volume or Full Colour Capability: OKI Pro 9542

For trade users who need to handle yellow rear plates, add dealer branding, or supply plates at higher volumes, the OKI Pro 9542 is the preferred choice. The white toner layer is the key differentiator — it allows printing directly onto yellow reflective material to produce a genuinely compliant, professional plate.

How Much Does Number Plate Printing Cost?

One of the most common questions from garages considering cheap number plate printing solutions is: what is the real cost per plate once you factor in equipment and consumables?

With an OKI-based system, the print cost per plate at typical volumes works out considerably lower than buying from a trade supplier, often paying for the printer investment within twelve to eighteen months depending on throughput. The reg plate printing page on OKI Supplies breaks down the economics clearly.

Getting Set Up: What to Expect

OKI Supplies supports garages and trade users through the full setup process. From helping you choose the right licence plate printer model to advising on software, consumables and ongoing support, the team can guide you from initial enquiry through to first print. You can also explore the full range via the license plate printing solutions page.

If you are ready to explore pricing or have questions about your specific requirements, the car number plate printing page is a good starting point, or you can contact the team directly for a tailored recommendation.

Summary: Is In-House Number Plate Printing Right for Your Business?

For any UK garage or motor trade business processing more than a handful of plates per week, in-house number plate printing is almost always the more cost-effective option. The OKI range makes it straightforward to produce compliant, professional plates reliably and at scale. Combine that with registration as an RNPS and you have a genuine revenue stream — not just a cost reduction.
