Quick answer — with a caveat we should state plainly: Erply's hardware documentation covers receipt printers, scanners, cash drawers and customer displays in detail. We did not find label printing documented to the same depth, and we are not going to describe a workflow we cannot point at.
What we can tell you is how labelling works in practice alongside a cloud POS, and the one rule that decides whether it works at all: the barcode on the label must be exactly the barcode recorded against the product in Erply. The NBBP-9250D (4″ desktop) handles batches; the NBBP-P581 (portable, Bluetooth) is for re-pricing on the shop floor.
Why labelling usually sits beside the POS, not inside it
This is not a criticism of Erply. It is how the category works, and understanding why makes the workflow obvious.
A receipt printer is part of the sale. The POS must drive it at the moment money changes hands, so a deep integration has to exist — which is why Erply runs a dedicated printing microservice for it.
A label printer is not part of the sale. Labelling happens when stock arrives, when prices change, or when a shelf edge is replaced — a stockroom job, not a checkout job. So POS vendors generally expose the thing that matters, the product list with its barcodes, and leave the printing to dedicated label software.
The upshot for buying: your label printer choice is driven by your labelling workflow rather than by which POS you run. That is genuinely liberating — there is no compatibility list to satisfy.
The one rule
The barcode you print must be exactly the barcode recorded against the product in Erply.
Everything else here is a preference. This is not. Get it wrong and the failure happens at the counter, in front of a customer, with a queue behind them.
The workflow that keeps it true:
- Set the barcode in Erply first — the supplier's EAN/UPC where one exists, or one you allocate for own-brand and loose goods.
- Export the product list with those barcodes.
- Print from label software using that export as the data source, at 100% scale.
- Scan one label back at the till before running the batch. Ten seconds, and it catches every category of error at once.
Step 4 is the one people skip and the one that saves the afternoon. It is also the step that catches the scanner-side problems — a symbology the scanner is not set to read will pass every visual inspection and still fail.
What to check on the barcode itself
- Symbology. EAN-13 or UPC-A for retail goods, Code 128 for internal codes. Confirm your scanner has that symbology enabled — most read all of these by default, but a scanner locked down to retail symbologies will silently ignore a Code 128 label.
- Quiet zone. The blank margin either side of the bars, and the first casualty of a label design that uses every millimetre. It is the most common cause of “it scans on some items and not others”.
- Scale. Always 100%, never “fit to page”. A barcode is a measurement, not a picture — scaling it to 97% produces something that still looks correct and reads unreliably, which is the most frustrating class of fault because it is intermittent.
- Print density. Too light and the bars break up; too dark and they bleed together. Both give you a code that scans at 5cm and fails at 20cm.
- Resolution versus size. A 13-digit EAN needs physical width. On small items, 300dpi buys readable bars in less space than 203dpi does.
Direct thermal or thermal transfer?
Direct thermal needs no ribbon and costs less per label, but it fades — with heat, with sunlight, with time. That is fine for a price label on fast-moving stock and wrong for an asset tag or a shelf edge that must stay readable for years.
If your labels live on a bright shelf edge, or on stock that sits for months, specify thermal transfer with a wax-resin or resin ribbon. It costs more per label and it is cheaper than re-labelling the shop.

Ordering advice: because labelling is independent of the POS here, choose by workflow. Batches at a desk → the 9250D. Walking the aisles → the P581 over Bluetooth. Small items with 13-digit barcodes → ask about the 300dpi option before you order. Send us a sample of the label you need and we will confirm resolution and media.
Frequently asked questions
Does Erply support label printers?
Erply's published hardware documentation covers receipt printers, scanners, cash drawers and customer displays in detail; we did not find label printing documented to that depth. If Erply has a label printing feature we have missed, tell us and we will correct this page. In the meantime, labelling alongside the POS works reliably and is what most cloud POS users do.
Then how do I label my stock?
Export your products with their barcodes from Erply, print labels from label software using that export at 100% scale, and scan one back at the till before running the batch.
Which barcode should I print?
Whatever is recorded against the product in Erply. Supplier EAN or UPC where one exists; otherwise allocate your own and record it in Erply first.
The label prints but will not scan.
Check scaling first — it must be 100%. Then the quiet zone, then print density, then whether the scanner has that symbology enabled.
Can I print labels from a phone or tablet?
Yes, with the portable P581 over Bluetooth — the usual arrangement for re-pricing on the shop floor rather than at a desk.
Do I need thermal transfer?
Only if labels must survive heat, light or time. Shelf-edge labels in a bright shop, and anything lasting more than a few months, justify the ribbon.
A note on this guide. The labelling side above — symbologies, quiet zones, scaling and bar widths, print density, direct thermal versus thermal transfer, resolution against barcode length — is what we know from the products we supply, and it holds regardless of POS software. On the Erply side we have deliberately not described a label printing feature we could not find documented, and we would rather say so than fill the gap with something plausible. If Erply does support label printers and we have missed it, tell us and we will correct this page. We would rather publish something accurate than something impressive.
