Quick fix: Print Spooler crashing usually means a corrupt print job or bad driver. Stop spooler: net stop spooler. Delete all files in C:\Windows\System32\spool\PRINTERS. Start spooler: net start spooler. Set service recovery: services.msc → Print Spooler → Recovery tab → First failure: Restart the Service. Removes problem permanently.

Print Spooler service stops on its own. Print jobs hang. Restarting service helps briefly, but it stops again. Cause: stuck print job, corrupt driver, or third-party print add-on crashing the spooler.

Symptom: Windows Print Spooler service repeatedly stops or crashes; can’t print until restart.
Affects: Windows 11 (and Windows 10) Print Spooler service.
Fix time: ~15 minutes.

What causes this

Print Spooler service queues and processes print jobs. Crashes happen when: stuck/corrupt job in queue, bad print driver, broken print monitor (DLL hook), or PrintNightmare-related vulnerability mitigations failing. Standard fix: clear queue + ensure auto-restart on crash.

Method 1: Clear stuck jobs and configure auto-restart

The standard fix.

Open Terminal (Admin).
Stop the service:
```
net stop spooler
```

Delete spooled jobs:

del /f /s /q C:\Windows\System32\spool\PRINTERS\*.*

Start the service:
```
net start spooler
```
Configure auto-restart on crash: services.msc → Print Spooler → Properties → Recovery tab. Set all three failure actions to Restart the Service. Apply.
Test print. If still crashes: identify cause via Methods 2/3.

Standard recovery sequence.

Method 2: Identify and remove bad printer driver

For driver-induced crashes.

Open Event Viewer (eventvwr.msc).
Navigate to Windows Logs → Application. Filter for source Application Error or spoolsv.exe.
Look at recent crashes. Often shows faulting module name — specific driver DLL.
Identify the driver: search filename online or check Printer Properties → Advanced for the driver name.
Remove the printer using that driver: Settings → Bluetooth & devices → Printers & scanners → pick printer → Remove device.
Remove the driver itself: Print Management (printmanagement.msc) → Print Servers → [local PC] → Drivers → right-click driver → Remove Driver Package.
Reboot. Spooler should be stable.
Re-add printer with fresh driver from manufacturer’s site (not Windows generic if possible).

This targets the root cause.

Method 3: Remove third-party print monitors and ports

For exotic crashes.

Open Registry Editor. Navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Print\Monitors.
List of installed print monitors: BJ Language Monitor, Local Port, Standard TCP/IP Port, USB Monitor, WSD Port.
For each non-default entry (anything besides the above): suspect. Common culprits: PDF print monitors, Canon language monitors, third-party fax monitors.
Right-click suspect monitor key → Export (backup). Then delete.
Restart Print Spooler.
Test print stability.
If stable: monitor was the cause. Keep removed.
If still crashes: investigate HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Print\Environments\Windows x64\Print Processors. Similar approach — keep only winprint; remove others.

This is the right path for exotic crashes.

How to verify the fix worked

Run Get-Service Spooler | Format-Table Name, Status, StartType. Status: Running, StartType: Automatic.
Print a test page. Completes without spooler crash.
Event Viewer → Application log: no new spoolsv.exe errors in past hour.

If none of these work

If spooler still crashes: Damaged spooler binary: run sfc /scannow. Repairs system files including spoolsv.exe. For PrintNightmare-related issues: Microsoft mitigations stricter on driver installation. Reinstall driver from latest manufacturer release. For network printers via WSD port: WSD can be flaky. Re-add printer using static IP and TCP/IP port instead. For PCs with many printers installed: cumulative driver bloat. Remove printers you don’t use. Less attack surface for crashes. For corporate environments: Print Server may be the actual cause. Contact IT. Last resort — reset Print subsystem: complete spooler reset via PowerShell:

Stop-Service Spooler -Force
Remove-Item C:\Windows\System32\spool\PRINTERS\* -Recurse -Force
Remove-Item HKLM:\SYSTEM\CurrentControlSet\Control\Print\Printers\* -Recurse -Force
Start-Service Spooler

Caution: removes all installed printers. Re-add fresh.

Bottom line: Stop spooler, clear PRINTERS queue, start spooler, set Recovery to Restart the Service. Identify problematic driver via Event Viewer. Remove non-default print monitors. Reinstall printer with fresh driver.
