If you are shipping more than a handful of parcels a week, a dedicated thermal label printer will save you a noticeable amount of time and ink costs. Thermal printers use heat rather than ink — no cartridges, no ribbons, labels in seconds. Here is how the main options compare.
Top thermal label printers compared

Do thermal printers work with UK couriers?
Yes, but there is one extra step for UK couriers. Royal Mail, DPD, Evri, and most other UK couriers generate labels as A4 PDFs — not in the 4x6 format that thermal printers expect. Before printing, you need to convert the label to 4x6 thermal format.
The free Label Resizer tool does exactly this: upload your A4 courier PDF, select 4x6 Thermal as the output, and download a correctly sized label ready to send straight to your thermal printer. No extensions, no account needed.
How much do thermal labels cost to run?
This is where thermal printers really win over inkjet and laser. A roll of 500 generic 4x6 thermal labels typically costs £5–£10, putting the per-label cost at 1–2p. Compare that to inkjet, where ink cartridge costs alone often work out at 5–15p per label — and that is before factoring in sticker paper. If you are shipping 20+ parcels a week, the savings add up quickly.
