Welcome to Microsoft Q&A!
Thank you for providing the details of the issue.
Based on your description, this behavior is commonly caused by a Print Spooler issue, a corrupted print queue, or an outdated or incorrect printer driver. I recommend trying the following troubleshooting steps:
1. Clear the print queue
- Open Settings > Bluetooth & devices > Printers & scanners.
- Select your thermal printer and open the print queue.
- Cancel all pending print jobs.
2. Restart the Print Spooler service
- Press Win + R, type services.msc, and press Enter.
- Locate Print Spooler.
- Right-click Print Spooler and select Restart.
3. Clear the spooler files
- Stop the Print Spooler service.
- Browse to:
C:\Windows\System32\spool\PRINTERS - Delete all files in this folder.
- Start the Print Spooler service again.
4. Reinstall the printer driver
- Remove the thermal printer from Printers & scanners.
- Download and install the latest driver available from the printer manufacturer's website.
- Re-add the printer and print a test page.
5. Check for driver conflicts
If this printer was installed previously, older printer drivers or print monitors may be interfering with the current installation. Removing any old printer instances and associated drivers before reinstalling can help resolve the issue.
6. Verify printer connectivity
- For USB-connected printers, try a different USB port or cable.
- For network-connected printers, confirm the printer is reachable on the network and that the correct printer port is configured.
If the issue persists after completing these steps, please check whether the Print Spooler service is stopping unexpectedly or whether the printer driver is compatible with your version of Windows. In many cases, clearing the spool folder and reinstalling the printer driver successfully resolves jobs that remain indefinitely in a "Spooling" or "Printing" state.
