4-inch vs 2-inch shipping label printers: which one do you need

This question comes up on almost every despatch setup, and the answer is usually simpler than people expect: if you're printing courier labels, you want 4-inch.

Why 4-inch is the default

Royal Mail, DPD, Evri and DHL all issue labels designed for a 104mm (4-inch) print width. Buying narrower to save money almost always means rebuying within the year, or scaling labels down until the barcodes scan unreliably.

A 4-inch printer also handles smaller labels perfectly well. The reverse is not true.

When 2-inch is the right call

Narrow printers earn their place on product barcodes, shelf-edge tickets, price labels and small asset tags. They're cheaper, take up less bench space and use cheaper media.

If you're labelling stock rather than parcels, 2-inch is often the better buy.

Direct thermal or thermal transfer

For parcels delivered within days, direct thermal is right — no ribbon, lower running cost. For labels that need to survive cold storage, sunlight or months on a shelf, thermal transfer resists fading and abrasion far better.

Specify for next year's volume

Media capacity is the specification people regret. A printer taking a larger roll runs longer between changes, and that gap widens during peak trading. Buy for roughly double your current volume.
