Common Causes

Thermal label printers are essential for point-of-sale (POS) systems, shipping stations, and retail counters across Brisbane. When your thermal printer stops printing labels, it can bring your checkout process to a halt. This guide walks you through the most common causes and how to fix them on a Windows POS system.

Quick Fix Steps

1. Check that the printer is powered on and all cables are securely connected.

3. Restart your Windows computer and the thermal printer.
4. Set the thermal printer as the default printer in Windows.
5. Print a test page to confirm the issue is resolved.

Detailed Instructions

1. Check Physical Connections and Power

1. Ensure the printer's power cable is plugged into a working power outlet and the printer is switched on.
2. Check the USB or Ethernet cable connecting the printer to your POS computer. If using a USB hub, try connecting the printer directly to the computer.
3. Look for any error lights on the printer. A flashing red or amber light often indicates a paper jam, open cover, or missing labels.

2. Load Labels Correctly

1. Open the printer cover and remove any existing label roll.
2. Insert a new roll of thermal labels, ensuring the labels feed from the bottom of the roll and pass under the print head.

4. Press the feed button (if available) to advance the labels and check for smooth movement.

2. Click Open queue.
3. Select any stuck print jobs and click Cancel, or click Cancel All Documents.

5. Run the Windows Printer Troubleshooter

Troubleshooting Common Issues

Printer Shows as Offline

If your thermal printer appears offline in Windows, check the physical connection and restart both the printer and computer. You can also try changing the printer port. For more help with offline printers, see our guide on Printer not printing / offline.

Blank Labels or Faded Printing

• Clean the print head with a lint-free cloth and isopropyl alcohol.
• Ensure you are using thermal labels compatible with your printer model.
• Check the printer's darkness or heat settings in the printing preferences.

Labels Feed but No Text Prints

This usually means the labels are loaded upside down or the wrong label size is selected in your POS software. Verify the label orientation and check that the paper size in your print settings matches the physical label roll.
