Dear Robert Bartels,
While older suggestions such as restarting the spooler service remain valid, recent updates to Windows 11 have introduced more reliable methods. We recommend clearing the spooler cache by stopping the Print Spooler service, deleting contents from C:\Windows\System32\spool\printers, and restarting the service. This can also be automated via a script to reduce manual effort.
Additionally, ensure that your Brother printer drivers are fully updated and compatible with Windows 11. You may also run the built-in Printer Troubleshooter via Settings > System > Troubleshoot > Other troubleshooters to detect and resolve spooler-related conflicts.
If the issue persists, consider setting the Print Spooler service to Automatic and configuring its recovery options to restart on failure. These adjustments have helped many users maintain stable printing environments.
Please let us know if you’d like assistance implementing these steps.
If my answer is useful for you, please give it a vote.
Best regards,
Quinnie Quoc.
