If you’re setting up a retail shop, pharmacy, or warehouse in Sri Lanka and need to print product labels and barcodes, this guide covers everything — without the technical jargon.
What Does a Barcode Printer Actually Do?
A barcode label printer prints adhesive labels with:
- Barcodes (for scanning at checkout)
- Product names and prices (for customers to see)
- Shelf labels (for store management)
- Shipping labels (for deliveries)
It prints on rolls of label paper — not regular A4 sheets. The labels are self-adhesive and you peel them off and stick them on products.
The Most Important Decision: Direct Thermal vs Thermal Transfer
This is where most buyers get confused. Here’s the simple version:
Direct Thermal
- No ribbon needed — the printhead heats the label paper directly
- Lower running cost — only buy label rolls
- Labels fade over time when exposed to heat, UV light, or friction
- Good for: Price tags, product labels, receipts — anything that doesn’t need to last years
Thermal Transfer
- Uses a ribbon — the printhead heats the ribbon, which transfers ink to the label
- Higher running cost — need to buy both label rolls and ribbons
- Labels last years — resistant to heat, UV, and chemicals
- Good for: Outdoor labels, equipment asset tags, labels that need to last long-term
For most Sri Lankan retail shops: direct thermal is the right choice. Your price labels change regularly anyway, and direct thermal labels last long enough for retail use.
Label Size: What Size Do You Actually Need?
This is the second most common mistake. Here are the standard sizes used in Sri Lankan retail:
| Label Size | Use Case |
|---|---|
| 30 × 20 mm | Pharmacy drug labels, small product tags |
| 40 × 20 mm | Most common retail price tag |
| 50 × 30 mm | Medium product labels |
| 58 × 40 mm | Larger product labels |
| 100 × 50 mm | Shelf edge labels |
| 100 × 150 mm | Shipping labels (4×6 inch) |
Most label rolls come in these sizes. Make sure the printer you buy supports the width you need — check the “label width” spec.
Connectivity: USB, Bluetooth, or Ethernet?
| Interface | What it means |
|---|---|
| USB | Cable connection to one computer |
| Bluetooth | Wireless from phone or tablet |
| Ethernet (LAN) | Connected to your network — multiple computers can print to it |
For a small shop using Invenova POS on one PC: USB is fine.
For a shop using a tablet or smartphone: choose Bluetooth (e.g. Niimbot B1 or XP-365B).
For a warehouse or large supermarket with multiple workstations: choose Ethernet (e.g. Rongta RP400H).

Do You Need a Receipt Printer Too?
Yes — a barcode printer is NOT a receipt printer. They do different jobs:
- Barcode printer prints labels on label roll paper
- Receipt printer prints customer bills on continuous receipt paper
Most retail shops need both. See our guide on choosing a receipt printer if you need both.
