Windows Print Spooler Stopped

Diagnose it

1. Check whether all Windows queues or only one application are affected.
2. Inspect the Print Spooler service status and recent Windows Event Viewer entries.
3. Record queued documents and application job identifiers.
4. Start or restart the service through approved administrative tooling.
5. Submit a small Windows test page.
6. If the service fails again, review recently installed or updated printer drivers and isolate suspect queues.
7. Use current, correctly matched, vendor-supported drivers.

About clearing the queue

Clearing spool files is destructive: jobs waiting in Windows will be lost and may need controlled resubmission. Do it only after identifying the affected queue, recording the jobs, stopping new submissions, and obtaining the appropriate administrative approval. Do not delete unrelated system files.

Application recovery

Show the workstation as degraded, retain immutable application jobs, and reconcile their state after spooler recovery. Retry with the original idempotency key where the printing layer supports it.

Verify

Print from Windows and the application, restart the workstation, and monitor the service under several representative jobs.
