General Troubleshooting Checklist
These basic checks apply to all Qashier-supported printers:
Confirm Power & Connectivity
For built-in printers, ensure your POS terminal is powered on and functioning normally.
For external printers, confirm the power light is on.
Ensure the POS terminal and printer are connected to the same WiFi network or properly linked via LAN.
Restart Devices
Restart the POS terminal, printer, and router (if applicable).
Unplug and reconnect power cables to reset the connection status.
Perform a Test Print
For built-in printers: Go to
Settings (3 line menu on the top right side) > Printer Settings > Test Print.For external printers: Press and hold the printer’s Feed/Test button to print a sample.
If test prints are blank, check for correct paper orientation and confirm you're using thermal paper (print side facing the thermal head).
Check Paper Roll
Ensure the thermal paper is loaded correctly.
Look for jams or depleted rolls.
Use only the supported paper size (e.g., 58mm or 80mm, depending on model).
Update POS Software
Please contact our Qashier Support team, and they will check if there are any updates available. If an update is required, it will be sent to your terminal, and a pop-up will appear on the screen prompting you to proceed with the update
📶 Fixing WiFi Printer Issues
If you're using a printer over WiFi and it fails to print:
Verify Same Network Connection
Both the POS terminal and the printer must be connected to the same WiFi network.
Go to
Settings (3 line menu) > Wifion the POS to check the current WiFi.
Restart Router, POS & Printer
Power cycle all devices at the same time to refresh connections.
Improve WiFi Signal
Move the printer closer to the WiFi router.
Avoid placing the printer behind walls or near microwave ovens or thick metal surfaces.
Check Tab Assignment
On the POS, go to
Settings > Printer Settings > Assign Tab.Make sure the printer is assigned to the correct function (e.g., Front Counter, Kitchen, Drinks).
Scenarios:
Unable to print the order chit, and the POS displays an error message
If the Wi-Fi router or Wifi password has been changed
Basic troubleshooting:
Restart the printer and check if it prints a small configuration slip.
Check the SSID (wifi network name) on the configuration slip.
On the POS, go to the Wi-Fi settings page and verify if it’s connected to the same SSID.
If not connected, connect the POS to the correct SSID.
Process a test transaction to confirm if the printer is working properly.
Ensure tab assignment (e.g., Kitchen/Drinks) is properly set.
Try performing a test print to verify connection stability.
If the issue persists:
Check if there are any changes to the Wi-Fi password or router
Restart the Wifi router, wait 3 to 5 minutes to refresh > test transaction
In case there are changes in the Wi-Fi router or password, reconfiguring the printer is necessary
Important note:
If your printer’s serial number starts with 23, 24, or 25, please do not perform a hard reset, as it may cause Wi-Fi errors. (This can be reconfigured directly without resetting.)
While the serial number starts with 21 or 22, hard resetting the printer may be necessary before reconfiguring it.
Reconnect Using Setup Guide
Reconfigure the printer via its IP address if needed.
Reminders:
The printer network name depends on the serial number:
23, 24, or 25 → Network name: “Printer Wifi”/”Wifi Printer”
21 or 22 → Network name: “E250*”**
🌐 Fixing LAN Printer Issues
If your printer connects via Ethernet and isn’t responding:
Check LAN Cable
Confirm the Ethernet cable is securely connected to the printer and POS/router.
Observe Network Indicator
A solid or blinking light typically indicates an active connection.
No light means the LAN may be disconnected or the printer isn't receiving data.
Feed & Restart Test
Turn off the printer.
Hold the Feed button and turn the printer back on.
Release the button after the beep and wait for a diagnostic printout.
Access Printer Network Settings
Use the printer’s IP address (shown in the test print) and access it via a browser.
Check that IP/Subnet/Gateway settings match your local network.
🧾 Troubleshooting Printing Output
If your printer is connected but not printing receipts or order chits properly:
Receipt Printing Issues
Confirm the POS is on the main home screen when trying to print.
Ensure the printer is assigned properly in printer settings.
💡 Pro Tips for Reliable Printing
Always test after making changes (e.g., restart, reassign tab, reconnect).
Keep the printer area clean and obstruction-free to avoid overheating or signal interference.
Maintain regular software and firmware updates for compatibility and stability.
