Our range of direct thermal labels compatible with the Zebra ZD421t Label Printer provides a fast, simple, and cost-effective solution for high-volume labelling. Using heat-sensitive material, these labels require no ink or ribbon, making them ideal for busy environments where efficiency and ease of use are key.
The Zebra ZD421t supports a maximum print width of 104mm, with label rolls up to 112mm wide (including backing paper) and a maximum roll diameter of 127mm. Our direct thermal labels are fully compatible with these specifications and are supplied on 12.7mm, 25mm, and 38mm cores, ensuring smooth feeding and reliable performance.
We stock a wide range of sizes, shapes, and colours, all available from stock for fast UK delivery. Our labels are available with a comprehensive selection of adhesives, including permanent for general use, removable for temporary labelling, high tack for more challenging surfaces, freezer-grade for chilled and frozen environments, and blockout adhesives for covering existing information.
Direct thermal labels are widely used across logistics, warehousing, retail, food labelling, and healthcare, where labels are typically required for short- to medium-term use. With no ribbon required, they help reduce consumable costs, minimise downtime, and simplify your labelling process, making them an excellent choice for shipping and dispatch operations.
While direct thermal labels do not require ribbons, the Zebra ZD421t Label Printer also supports thermal transfer printing. For applications requiring greater durability, we supply a full range of thermal transfer ink ribbons for the Zebra ZD421t printer, including ZD421t-compatible ribbons in the UK such as wax, wax/resin, and resin grades, ideal for use with paper or synthetic labels where longer-lasting print is needed.
In addition to direct thermal labels, we also supply thermal transfer paper labels and synthetic labels for more durable applications, giving you complete flexibility depending on your requirements.
To help optimise your workflow, we offer a full range of accessories including label rewinders, label applicators, label dispensers, label design software, and barcode scanners, everything you need to build an efficient print and apply system around your Zebra ZD421t.
If you’re unsure whether direct thermal labels are the right choice for your application, or need help selecting the correct size or adhesive, our team is always on hand to help.
