Troubleshooting Printing Issues
If your printer is not working with the kiosk or application, follow the steps below to identify and resolve the issue.
Issue: Print Doesn’t Work
Case 1: Printer Model is Available In-House
If the same printer model is available for internal testing:
Replicate the issue internally to understand the behavior
Check if the printer plugin application is installed on the client’s kiosk
If not, install it from the Google Play Store
Perform a test print using the plugin
If the test print is successful, try printing from the Qwaiting application using the same plugin
If the issue still persists, escalate to the Development/QA team
Case 2: Printer Model is NOT Available In-House
If the printer model is not available for testing:
Try configuring the printer using ESC/POS settings from the backend
If it still does not work, the printer’s SDK integration may be required
Common Scenario: Printer Prints Blank Paper
If the printer is printing blank receipts, the issue is usually due to incorrect paper roll installation
Ensure the paper roll is placed in the correct direction
Still Not Working?
Try printing directly from a web browser
If printing fails there as well, the issue is likely device or printer-related
Next Steps
Share the Device Serial Number (SN) with the support team
The team will:
Verify your device
Check and apply necessary firmware updates
Review and update BIOS-level configurations (if applicable)
Note:
BIOS-related configurations apply only to supported kiosk/PC devices
For Android devices, equivalent system-level configurations will be applied
