Barcode label printing for supermarkets in Oman looks simple until the first busy weekend: labels that will not scan, shelf tags that fade under the lights, and prices on the shelf that do not match the till. Most of these problems come from three early choices: the label size, the type of printer and the barcode you put on the label. This guide explains each choice in plain terms so a supermarket, hypermarket or grocery owner can set it up correctly the first time.
Where a supermarket actually needs labels
Before buying a printer, list the jobs it has to do. A typical store has four different labelling jobs, and each one has its own best label.
- Shelf edge labels showing the item name, price and barcode for each product facing.
- Item labels for products that arrive without a barcode, such as local sweets, repacked nuts and spices, household items and goods packed in store.
- Weighed goods labels printed by the scale at the fruit, vegetable, meat, cheese and roastery counters.
- Carton and stockroom labels used for receiving, back-store locations and transfers between branches.
Trying to cover all four with one roll of labels is the most common mistake. Two or three label sizes, each loaded in the right printer, cost less in the long run than reprinting and re-sticking.
Choosing barcode label sizes for shelves and products
Retail products around the world carry the EAN-13 barcode. Under the GS1 standard, a full-size EAN-13 symbol is about 37 mm wide including the blank margins on each side, and it may be reduced to 80 percent, which is about 30 mm wide. That single fact sets your minimum label width: a label narrower than roughly 32 mm leaves no room for a standard barcode to scan reliably.
The sizes below are widely used in retail and are a sensible starting point. Your label supplier may offer slightly different dimensions.
| Use | Common label size | What fits on it |
|---|---|---|
| Small item label | 38 x 25 mm | Barcode, short name, price |
| General item label | 50 x 25 mm or 50 x 30 mm | Barcode, Arabic and English name, price |
| Shelf edge label | Width to suit the item, height to suit your shelf rail | Large price, both names, barcode |
| Weighed goods label | 58 x 40 mm, depending on the scale | Weight, price per kilo, total, packing date |
| Carton label | 100 x 50 mm or 100 x 150 mm | Item, quantity, batch, large barcode |
Measure your shelf rail before ordering shelf labels, because rails differ between shelving suppliers. Two rules apply to every size. First, keep a clear blank margin on both sides of the barcode. Second, do not cut the height of the bars to make room for text; GS1 advises against this because shorter bars are harder to scan. Black bars on a white label remain the safest combination.
Direct thermal or thermal transfer printers
Label printers work in one of two ways, and the difference matters in Oman's climate.
- Direct thermal printers use heat-sensitive labels and no ribbon. They are simple and economical, but the print fades with heat, sunlight and rubbing. They suit short-life labels: weighed goods, fresh food and fast-moving items.
- Thermal transfer printers melt ink from a ribbon onto the label. The print lasts far longer, so they suit shelf labels that stay in place for months, products near windows, chilled and frozen sections, and the stockroom.
Many desktop models can do both, which gives you flexibility. When you compare printers, check three more points:
- Print width. A 4-inch (about 104 mm) printer handles every size in the table above.
- Resolution. 203 dpi is enough for standard labels. Choose 300 dpi if you print very small labels or small Arabic text.
- Daily volume and connection. A desktop printer is fine for a few hundred labels a day. A store printing thousands should look at an industrial model. Choose Ethernet if several computers will share the printer.

Barcodes for products without a manufacturer code
Branded and imported goods already carry a barcode. Do not relabel them; scan the existing code into your item list when you receive the goods. Labels are needed only for the rest.
- Items packed in store. Your POS or ERP system can generate internal barcodes. In the GS1 system, numbers starting with the digit 2 are set aside for restricted, in-store use, which is why most retail systems use them for internal items.
- Weighed items. A label-printing scale produces a barcode with the item code and the weight or price inside it. The scale and the POS must use exactly the same barcode format, so agree the format before you buy the scales.
- Your own brand. If you pack products that other retailers will sell, internal codes are not enough. You need registered numbers, which are issued in the Sultanate by GS1 Oman.
Arabic text and prices that match the till
Oman's consumer protection rules require the selling price to be shown clearly and in Arabic, with other languages allowed alongside it, and they prohibit charging more than the displayed price. For a supermarket this turns label printing into a daily discipline rather than a one-time setup.
- Enter every item with an Arabic name and an English name, so both print on the label.
- Test your label design with real Arabic names. Long names need a second line, not a smaller font.
- Print labels from the same database the tills use. Retyping prices into separate label software is how mismatches begin.
- When a price changes, print the new shelf labels the same day and replace them before opening.
- Show the final price the customer pays at the till.
A retail system such as iMPOS, connected to Riyalo ERP for purchasing and stock, can list the items whose prices changed today and print only those labels. Rules can change, so confirm current requirements with the Consumer Protection Authority.
Frequently asked questions
Can I print barcode labels on a receipt printer?
A receipt printer is built for continuous paper, not for labels with gaps between them. For regular labelling, a dedicated label printer positions each label accurately and wastes far fewer labels.
Do I need GS1 registration to label items in my own shop?
No. Internal codes are fine for products sold only in your own branches. Registration becomes necessary when your products are sold through other retailers or exported.
How many label printers does one supermarket need?
A small store usually manages with one desktop label printer in the back office plus label-printing scales at the fresh counters. Larger stores often add a second printer at goods receiving so that shelf labels and carton labels do not wait for each other.
