The Windows Print Spooler service is essential for managing all print jobs sent to a printer. When this service encounters errors, it can halt printing tasks and disrupt workflows. This list covers common Print Spooler service error codes along with practical solutions, designed specifically for IT professionals, system administrators, and everyday users troubleshooting printing issues on Windows systems.
Error Code 0x800706b9: No More Endpoints Available
This error occurs when the Print Spooler service fails to communicate with the printer due to a shortage of RPC (Remote Procedure Call) endpoints. It often happens in networked environments where multiple print jobs or connections overwhelm the spooler. Resolving this typically involves restarting the Print Spooler service and checking for network connectivity issues or RPC service failures.
Error Code 0x8007007e: Module Not Found
Error 0x8007007e indicates that a required DLL or driver file for the Print Spooler is missing or corrupted. This can happen after a Windows update or driver installation failure. Fixing it requires reinstalling or updating the printer driver and running system file checks (SFC) to repair corrupted system files.
Error Code 0x80070005: Access Denied
This error suggests that the Print Spooler service lacks sufficient permissions to access printer drivers or spooler files. It can occur if user privileges were changed or if malware altered permissions. The solution involves adjusting security settings, ensuring the Spooler service runs under the correct account, and sometimes resetting the printer driver permissions.
Error Code 0x800706d9: Windows Firewall Block
Error 0x800706d9 happens when the Windows Firewall blocks communication needed by the Print Spooler, especially in network printing scenarios. Disabling or misconfiguring the firewall can prevent the spooler from sending print jobs. To solve this, confirm that firewall rules allow spooler service traffic or temporarily disable the firewall to verify if it’s the cause.
Error Code 0x80070032: The Request Is Not Supported
This error arises when an unsupported operation is requested on the Print Spooler, often due to incompatible printer drivers or corrupted print queue data. It can also appear after a Windows update changes how certain drivers behave. Clearing the print queue and updating or replacing printer drivers usually resolves this issue.
Error Code 0x800706b5: The Endpoint Is Not Connected
Error 0x800706b5 points to a failure in establishing communication between the print spooler and the printer device. This can be caused by network interruptions, printer offline status, or driver conflicts. Ensuring the printer is online, reinstalling drivers, and restarting related services are the recommended fixes.
Error Code 0x000006e4: RPC Server Unavailable
This error specifically indicates that the Print Spooler cannot reach the RPC server required to process print jobs. Common causes include network issues, RPC service stoppage, or firewall blocking RPC ports. Verifying RPC service status, network connectivity, and firewall exceptions resolves this error.
Error Code 0x00000057: Parameter Is Incorrect
Error 0x00000057 occurs when the Print Spooler receives invalid parameters during a print job request, often caused by driver incompatibility or corrupted print job files. Users can fix this by deleting stuck print jobs, reinstalling printer drivers, and ensuring drivers match the operating system architecture.
Error Code 0x800705b4: Operation Timed Out
This error signifies that the Print Spooler service timed out waiting for a response from the printer or print server. It commonly happens in network printing or when the printer is busy or unresponsive. Troubleshooting steps include restarting the spooler, checking printer status, and verifying network connectivity.
Error Code 0x80070020: The Process Cannot Access the File Because It Is Being Used by Another Process
This error appears when a print job or spooler file is locked by another process, preventing the Print Spooler from accessing it. Often caused by stuck print jobs or antivirus software scanning spooler files, this can be resolved by clearing the print queue, restarting the spooler service, and temporarily disabling conflicting software.
How to Choose
Choosing the right approach to fix Print Spooler errors depends on accurately identifying the error code and understanding its root cause. Prioritize solutions based on the environment: networked setups may require firewall and RPC checks, while local printing issues often stem from driver problems or corrupted spooler files. Always begin with restarting the Print Spooler service and clearing the print queue, then move to driver updates or system file repairs. For persistent or unclear errors, reviewing Windows Event Logs can provide deeper insight to select an effective fix.
Frequently Asked Questions
Q: How do I restart the Print Spooler service?
Open Services (services.msc), locate “Print Spooler,” right-click, and select “Restart.” This often clears temporary errors.
Q: Can outdated printer drivers cause spooler errors?
Yes, incompatible or outdated drivers are a common cause of many Print Spooler errors. Keeping drivers updated helps maintain stability.
Q: Is it safe to delete all files in the spooler folder?
Yes, deleting files in C:\Windows\System32\spool\PRINTERS while the spooler service is stopped can clear stuck print jobs without harming your system.
Q: What role does the RPC service play in printing?
The Remote Procedure Call (RPC) service enables communication between the Print Spooler and printer devices or servers. If RPC is down, printing often fails.
Q: Why does the Print Spooler crash repeatedly?
Repeated crashes can be caused by corrupted printer drivers, malware, or conflicts with other software. Updating drivers and scanning for malware are recommended first steps.
Final Thoughts
Print Spooler service errors can be frustrating but are often resolvable with systematic troubleshooting. Understanding specific error codes helps target the root cause, whether it’s driver issues, network problems, or permission conflicts. Regular maintenance—such as keeping drivers current, monitoring service status, and ensuring network stability—minimizes spooler disruptions. Armed with these error codes and solutions, users and IT professionals can restore printing functionality efficiently and reduce downtime.
