Label printers: the buying criteria that actually matter
The brand matters less than the job. Print width, resolution, print method, daily volume, roll size and printer language: the criteria that stop you buying a printer you'll have to replace.
Label printers are often bought on brand or price. The nasty surprises come from elsewhere: a printhead that's too narrow, a roll that won't fit, software that doesn't speak the right language. Here are the criteria in the order they rule models out.
1. What you print
| Job | Printer type | Labels |
|---|---|---|
| Parcels, carriers (Royal Mail, Evri, DPD) | 4-inch, direct thermal | 100 × 150 mm (6 × 4) |
| Product barcodes, prices | 2- or 4-inch, direct thermal | 30 × 20 to 60 × 40 mm |
| Stock, locations, assets | 4-inch, thermal transfer | Coated paper, PP |
| Long-life labels, rating plates, chemicals | 4-inch, thermal transfer, resin ribbon | PP, polyester, Silvermat |
2. Print width
A 2-inch head prints about 54 mm wide, a 4-inch head about 104 mm. If a 100 mm wide label is ever on the cards, buy 4-inch from the start: it prints the small sizes too. Our label size guide lists sizes by job.
3. Resolution: 203 or 300 dpi
- 203 dpi (8 dots per mm) is enough for parcel labels, normal-size EANs and everyday text.
- 300 dpi (about 12 dots per mm) pays off for small labels, small type, small Data Matrix and QR codes, or fine logos.
The real test: the narrowest bar in a barcode should land on a whole number of dots. There's a worked example in our guide to SSCC pallet labels.
4. Direct thermal or thermal transfer
A printer with a ribbon holder does both; without one, it's direct thermal only. If labels have to last, or cope with cold and solvents, you need thermal transfer. Full comparison: direct thermal or thermal transfer.
5. Daily volume
| Volume | Category |
|---|---|
| A few dozen to a few hundred labels a day | Desktop printer |
| Several thousand a day, multiple shifts | Industrial printer (metal frame, large rolls) |
| Automatic labelling on a line | Print-and-apply system |
A desktop printer pushed beyond its duty wears out fast: printhead, platen roller, sensors.
6. Roll size
- Core: 25 or 38–40 mm on desktop printers, 76 mm on industrial ones.
- Maximum outside diameter: about 127 mm on many desktop models, up to about 203 mm on industrial printers.
Bigger rolls mean fewer changes. Details in label core and winding.
7. Language and software
ERP, warehouse systems and carrier platforms often send labels in ZPL, the Zebra printer language that many other brands emulate. Before buying, check that your software or carrier can drive the model, or that a Windows/macOS driver will do.
8. Connectivity and options
USB for a single workstation, Ethernet or Wi-Fi to share it, Bluetooth for mobile devices. Useful options: a peeler (labels come out already separated from the liner), a cutter, a black-mark sensor.
Common mistakes
- Buying a 2-inch printer, then needing to print 6 × 4.
- Choosing a printer without a ribbon holder when labels need to last.
- Ignoring the printer language: the ERP can't print.
- Running a desktop model at industrial volume.
Consumables
Our thermal labels are wound on a 40 mm core, compatible with Zebra desktop printers and most common models; for thermal transfer, see our blank rolls.
FAQ
2-inch or 4-inch?
4-inch as soon as you might need a 100 mm wide label, such as 6 × 4 parcel labels.
203 or 300 dpi?
203 dpi is enough for parcels and normal EANs; 300 dpi for small labels, small type and small 2D codes.
Does my printer need to take a ribbon?
Yes, if labels have to last or withstand cold and solvents: that's thermal transfer.
What is ZPL?
The Zebra printer language, used by a lot of software and emulated by other brands.
Do your rolls fit a Zebra desktop printer?
Yes, our thermal labels use a 40 mm core, compatible with Zebra desktop printers.
