Print barcode and QR labels
Stick a label on every item so your cashier can scan it at the POS. POSMaster prints barcodes and QR codes on normal A4 sticker sheets or on a label printer roll. Open it from Catalogue → Print labels. You need the labels.print permission.
Add products to the label list
- In the search box (Search product or scan barcode to add…) type a name, SKU or barcode. Click the product, or press Enter to pick the first suggestion.
- Or scan the barcode of a product with your scanner. The product is added to the list.
- Repeat for every product that needs labels. Adding the same product again increases its number of labels by one.
- In the Labels column type how many labels you want for each row (1 to 500).
- Use ✕ to remove a row.
Every variant is a separate row, because each variant has its own barcode. A quick way to print all the variants of one product: open the product page and click Print labels. All its variants are added for you with 1 label each.
Choose the options
On the right side, under Options:
| Option | Choices |
|---|---|
| Code | Barcode, QR code or Barcode + QR |
| Sheet | A4 — 24 per sheet (3×8), A4 — 40 per sheet (4×10), A4 — 65 per sheet (5×13) or Label printer roll (50×30 mm) |
| Product name | Print the product (and variant) name |
| Price | Print the selling price |
| Business name | Print your business name from Settings → Business |
- The barcode follows the type set on the product (EAN-13 or Code 128) and prints the number under it.
- The QR code contains the product SKU. Both the barcode and the QR code are recognised by the POS scanner and camera.
- 24 per sheet gives big labels (64 × 34 mm), 40 per sheet is the usual choice (48 × 26 mm) and 65 per sheet gives tiny labels (38 × 21 mm), which only fit a short name and a barcode.
Preview and print
- Click Preview & print. The labels open in a new browser tab so you can check them. The button at the top shows how many labels will be printed, for example Print (40).
- Click Print. The browser print window opens.
- Choose your printer and apply the settings below.
Print settings that matter
For labels to line up with the stickers, set these in the print window:
- Scale: 100% (also called "Actual size"). Do not use "Fit to page" or "Shrink to fit".
- Margins: None. The page already contains its own spacing.
- Paper size: A4 for sheet labels. For the roll, choose a custom size of 50 × 30 mm (in your label printer's driver).
- Turn off Headers and footers so the date and web address are not printed on the labels.
- Turn on Background graphics if the barcode looks too light.
Tip: Print one test page on plain paper and hold it against a sheet of stickers to the light before you waste labels.
Note: On the roll layout, each label is its own page, so the printer cuts or advances one label at a time.
Warning: If barcodes do not scan, the label is usually printed too small or blurred. Use the 24 or 40 per sheet layouts, a good printer quality and 100% scale.
