“A printer spooler error fix is easier than most people expect. The Windows Print Spooler service is a background process that manages all print jobs — when it stops or crashes, your printer stops working even though the hardware is perfectly fine. In 2026, this remains one of the most common Windows printing issues in both home offices and business environments. The fastest fix is to restart print spooler from the Services window, then clear the print queue folder at C:\Windows\System32\spool\PRINTERS. If the print spooler stopped condition keeps returning, a corrupted driver or a recent Windows update is usually the cause. This guide walks you through 10 proven fixes — from a simple print spooler service restart to a full port reinstall — so you can get back to printing quickly, without calling IT support.”
You attempt to print something. Nothing happens. You go to the printer—it is powered on, connected, and has no error message. However, if you check the Windows print queue, you will find that all your jobs remain in the queue and are not moving. Or you will get an error message in Windows saying that the Print Spooler service is not running.
A printer spooler error fix is a must-have for every Windows user on the planet, and it is one of the most aggravating printer problems in a Windows office environment because the printer itself is not the problem—it’s a background service (spooler) running in Windows that handles all print jobs. Network printers are prone to spooler issues. The upside is that, if you know where to look, you can fix a printer spooler error without calling IT support.
The following are 10 effective solutions to print spooler errors for Windows 11 and Windows 10 — from the quickest to the most extensive. Solve them in order.
What is the Print Spooler?
The Windows Print Spooler (also called the spooler subsystem) is a background service that receives print jobs from your computer, holds them in a queue, and sends them to the printer in order. When it stops or crashes, print jobs pile up and nothing prints — even though the printer is working perfectly. This is commonly referred to as a spooler subsystem app error. Spooler errors can make printer showing offline.
Why Does the Print Spooler Error Happen?
When the printer not printing issue arises due to a spooler failure, you should be able to choose a proper fix and avoid the reoccurrence.
- A job is stuck in the print queue, causing a print job to corrupt and block the entire queue.
- A conflicting program stopped the Print Spooler service from starting.
- A Windows update modified some settings that are relevant to using the spooler.
- The printer driver is outdated or corrupted, causing data to be sent to a corrupt spooler.
- Corrupted temporary files have built up in the spooler folder due to failed print jobs.
- A driver conflict has occurred due to a hardware change (new printer, new USB port).
Now that you know the likely cause, here are the 10 printer spooler error fixes — starting with the simplest.
How to Fix Printer Spooler Errors on Windows 10
Fix 1: Restart the Print Spooler Service (Start Here)
This is the fastest printer spooler error fix for most situations and resolves the problem about 60% of the time. The Print Spooler service can stop on its own due to a failed print job or a driver crash—restarting it clears the issue.
- Press Windows + R on your keyboard to open the Run dialog
- Type services.msc and press Enter — the Services window opens
- Scroll down the list to find Print Spooler
- Right-click Print Spooler and select Restart Print Spooler
- If Restart is grayed out, click Stop first, wait 5 seconds, then click Start
- Close the Services window and try printing again
If the Print Spooler service restarts successfully and print jobs still do not move, continue to Fix 2.
Fix 2: Clear the Stuck Print Queue
A corrupted print job stuck in the queue will block every subsequent print job. Even after you restart print spooler, a corrupted job sometimes reloads from the spooler folder and blocks the queue again. You need to clear the print queue manually.
- Open Services (Windows + R, type services.msc, press Enter)
- Find Print Spooler, right-click it, and select Stop — leave the Services window open
- Open File Explorer and navigate to: C:\Windows\System32\spool\PRINTERS
- Select all files inside this folder (Ctrl + A) and delete them — do NOT delete the PRINTERS folder itself, only the contents
- Go back to Services, right-click Print Spooler, and select Start
- Try printing again
This two-step process — stopping the spooler, clearing the folder, restarting the spooler — resolves the vast majority of print queue stuck issues.
Fix 3: Set Print Spooler to Start Automatically
If the printer spooler error keeps coming back every few days, the print spooler has stopped starting automatically when Windows boots. Fix printer not printing issues; spooler errors cause printer-not-printing symptoms. This means the spooler runs fine until Windows restarts—then it does not come back on its own.
- Open Services (Windows + R, services.msc, Enter)
- Find Print Spooler and double-click it to open Properties
- Change the Startup Type dropdown to Automatic
- Click Apply, then OK
- If the service Status shows Stopped, click Start
- Click OK and close Services
Changing the startup type to Automatic means Windows automatically starts the Print Spooler service every time the computer boots — preventing the recurring printer spooler error.
Fix 4: Update or Reinstall Your Printer Driver
A bad or old printer driver is a very common reason for printer crashers. The print spooler stopped working because data from the driver application could not be handled by the spooler. Driver reinstall often fixes spooler errors. The solution is to reinstall the driver from the printer manufacturer’s official website.
- From Settings, select Bluetooth and devices > Printers and scanners
- Click on your printer and choose Remove device.
- Visit the official support website of your printer’s manufacturer (hp.com, canon.com, brother.com, epson.com)
- Look for your printer type and download the latest full driver package for Windows 10 or Windows 11.
- Execute the installer and follow the directions on screen
- Once installed, restart your computer.
- Print a test page to ensure that the printer spooler error fix has been completed.
Always get drivers from the manufacturer. Third party driver sites often contain old or modified drivers that lead to just these sorts of problems that you’re trying to resolve.
Fix 5: Run the Windows Printer Troubleshooter
A built-in printer troubleshooter is included in Windows 10 and Windows 11 to automatically identify and correct common printer issues. It won’t fix all printer spooler issues, but it can be done in less than 2 minutes and it can save you from the manual process described above at times.
- Open Settings (Windows + I)
- In the system menu, select Troubleshoot > Other troubleshooters.In the system menu, click on Troubleshoot > Other troubleshooters.
- Locate Printer in the list and then click Run.
- Follow on-screen instructions, apply any recommended fixes by the troubleshooter.
- Restart computer and test printing.
Fix 6: Check for Conflicting Printer Software
When multiple brands of printers have been installed over time on the same computer, remnants of the previous printer software may interfere with the current printer’s spooler communication. This is particularly a common problem in offices that changed printer brands without uninstalling the previous printer software and leads to the printer not printing problems to occur again and again.
- To uninstall a program, go to Open Control Panel > Programs > Uninstall a Program.
- Scan for old printer software (HP software, Canon software for an old printer, etc.).
- Remove all printers software from unused printers
- Restart your computer
- If the printer driver installation was not successful, repeat the printer driver installation for your current printer.
Fix 7: Use the Command to Repair the Spooler
If the errors in the printer spooler persist and the service can’t be restarted, this command prompt method resets the printer spooler subsystem and re-registers the DLLs required by the spooler. This is one of the best methods to handle a spooler subsystem application error manually.
Right click on the Start menu and click on Windows Terminal (Admin) or Command Prompt (Admin). Run these commands one at a time:
net stop spooler del /Q /F /S %systemroot%\System32\spool\PRINTERS\*.* net start spooler rundll32 printui.dll,PrintUIEntry /s /t2
After running these commands, close Command Prompt and try printing. This is one of the most thorough spooler reset methods available without reinstalling Windows.
Fix 8: Check Windows Event Viewer for the Exact Cause
When the printer spooler fails repeatedly after several restart print spooler attempts, Windows Event Viewer indicates the reason why the printer spooler is failing, and it tells you which DLL, driver or process is causing the printer spooler failure.
- Click on Windows + X and choose Event Viewer.Click Windows + X and then select Event Viewer.
- In the left pane, double-click Windows Logs and then select Application.
- Check the Error entries in the time period around when the print spooler stopped (the times should match when you noticed the issue)
- Click on each Error and read the General tab description
- Pay attention to the name of the DLL file or the application that appears in the error – this will guide your IT provider in determining what to fix.
Fix 9: Check for a Windows Update That Changed Spooler Settings
Microsoft has published print spooler stopped and Windows updates which mistakenly altered the print spooler security settings. The spooler is no longer automatically started or blocks some printer connections.
- Go to Settings > Windows Update > Update History
- Note any updates installed in the 24 to 48 hours before the printer spooler error started
- Search the specific KB update number online to see if it has known printer or spooler issues
- If the update is confirmed to cause spooler problems: Settings > Windows Update > Update History > Uninstall Updates > find and uninstall the specific update
- Restart your computer and confirm the spooler is working
Fix 10: Reinstall Windows Printer Ports
In some cases, the printer spooler error is tied to a corrupted printer port rather than the Print Spooler service itself. Deleting and recreating the printer port can resolve a printer not printing situation that survives every other fix.
- Open Settings > Bluetooth and devices > Printers and scanners
- Remove the printer completely
- Open Devices and Printers from Control Panel
- Click Print server properties at the top of the page
- Go to the Ports tab, find any ports associated with your printer, and remove them
- Close everything and add the printer back from scratch using the printer driver you downloaded from the manufacturer site
When to Call IT Support for a Printer Spooler Error
You should call IT support when: you have followed fixes 1-5 and the printer spooler error occurs within 24 hours; an event in the Event Viewer is a DLL or system file error that you cannot interpret; the Event Viewer displays an error on multiple computers within your office network (a network print server or server side error – not a local PC error).

Frequently Asked Questions
The printer spooler error in the Windows System Services is a background service that controls all Windows printer queues and has stopped, crashed or stuck in the queue on a corrupted Windows print job. The printer is generally OK. The issue is with the Windows service that handles the communication between your computer and printer.
Open the “Services” window by pressing Windows + R, and typing “services.msc”. Go to the Services list and right click on Print Spooler and choose Restart Print Spooler. If Restart is grayed out, click Stop, pause for 5 seconds and then click Start. Attempt to print once service is back on. This is the quickest print spooler error repair that is available on print spooler Windows 11.
A print spooler stopped condition that keeps recurring is almost always caused by a corrupted printer driver, leftover files in the spooler folder from failed print jobs, or a Windows update that changed spooler configuration. The most reliable printer spooler error fix is to clear the print queue folder (C:\Windows\System32\spool\PRINTERS), reinstall the printer driver from the manufacturer’s site, and set the Print Spooler service Startup Type to Automatic.
The print spooler service itself doesn’t process your document in such a way that it causes data loss – your original document remains unaffected. But if an error occurs in the spooler subsystems, the documents may be sent partially to the printer, causing garbled printouts. Any of your original files will be safe on the computer.
Conclusion
A printer spooler error fix does not have to mean a call to IT support or a lost workday. In most cases, the solution comes down to three straightforward actions: restart print spooler, clear the print queue folder, and confirm your printer driver is current. These three steps alone resolve the overwhelming majority of cases where the print spooler stopped or a print job stuck in the queue has brought printing to a halt.
If the problem keeps coming back, the 10 fixes in this guide take you deeper — from setting the Print Spooler service to start automatically, to resolving a spooler subsystem app error through the Command Prompt, to identifying the root cause in Windows Event Viewer. Whether you are on print spooler Windows 11 or Windows 10, every fix here is designed to be completed by a non-technical user without special tools.
Work through the fixes in order, and in most cases your printer not printing issue will be resolved before you reach Fix 5. If you have tried every step and the printer spooler error continues, it is time to bring in professional support — and Ovron Inc is ready to help.
