What this means

Error 0x00000006 means the handle is invalid. Windows is trying to talk to your printer, but the communication channel is broken. A handle is simply the active line of communication between your computer and the printer. When that line snaps, or when Windows points to a print spooler reference or registry entry that no longer works, the connection fails.

Your printer hardware is fine. You are not out of ink. The problem stems from software issues like a crashed Print Spooler service, stuck print queues, outdated drivers, or corrupted printer port registry entries. Network shifts cause this too. If your network printer changes its IP address, or if a shared printer sits on a host computer that went to sleep, the link drops.

Windows updates can also break legacy driver communications. Because this error points to a lost connection handle instead of a dead machine, restarting your computer often forces Windows to reinitialize the system and rebuild the broken link.

Common causes

  • Print spooler service has stopped or crashed
  • Corrupted printer driver installation
  • Stale network printer mapping
  • Registry corruption in printer ports
  • Outdated Windows print subsystem components
  • Network disconnection during an active print job

What to check first

  1. 1Restart both your computer and the printer
  2. 2Verify network connectivity if using a network printer
  3. 3Check if other applications can print successfully
  4. 4Ensure the printer is set as active and not paused

Step-by-step fix

  1. 1

    Restart the Print Spooler Service

    Open the Run dialog by pressing Windows Key plus R, type services.msc, locate Print Spooler, right-click and select Stop. Navigate to C:\Windows\System32\spool\PRINTERS, delete all files inside, then go back to Services and Start the Print Spooler.

  2. 2

    Remove and Re-add the Printer

    Open Windows Settings, go to Bluetooth and devices, then Printers and scanners. Select the problematic printer, click Remove device, and then click Add device to reinstall it.

  3. 3

    Run the Printer Troubleshooter

    Open Windows Settings, navigate to System, then Troubleshoot, and click Other troubleshooters. Run the Printer troubleshooter and follow the on-screen prompts.

  4. 4

    Update or Reinstall Printer Drivers

    Download the latest driver package from the manufacturer website, uninstall the current driver through Print Management or Device Manager, and install the fresh package.

  5. 5

    Clear Old Printer Ports via Print Management

    Type printmanagement.msc in the Run dialog, navigate to Print Servers, select your computer name, click Ports, and remove any orphaned or invalid ports.

When to contact a professional

Call your system administrator if a corporate domain policy or Active Directory restriction controls your printer. Reach out to IT if persistent registry errors block a reinstall.
