What this means

Error 0x0000007a means your computer cannot communicate with a shared network printer on a Windows print server. Windows throws a specific message stating that the data area passed to a system call is too small.

Do not assume your document is too large. The error has nothing to do with the physical size of your print job. It refers to system level data packet handling.

The problem comes down to driver mismatches or security restrictions between your machine and the server. Windows security updates affecting Point and Print policies regularly trigger this communication block. This is an operating system failure, not a physical printer problem.

Common causes

  • Windows security updates affecting Point and Print restrictions
  • Driver architecture mismatch between client and print server
  • Corrupted local printer driver cache on the client machine
  • Outdated print server drivers incompatible with modern Windows RPC requirements
  • Restrictive Group Policy settings blocking driver downloads from the server
  • Stale or corrupted Windows Credential Manager entries for the print server
  • Print Spooler service hanging or failing to handle the RPC packet size

What to check first

  1. 1Verify basic network connectivity between the client PC and the print server
  2. 2Confirm you have administrative privileges on the local machine to install drivers
  3. 3Check if other network users are experiencing the same printer connection error

Step-by-step fix

  1. 1

    Restart the Print Spooler Service

    Open the Services app, locate Print Spooler, right click and select Restart. Do this on both the client machine and the print server if you have access.

  2. 2

    Clear the Local Printer Driver Cache

    Stop the Print Spooler service, navigate to C:\Windows\System32\spool\drivers\x64\3, delete lingering temporary files, and restart the spooler.

  3. 3

    Remove Stored Credentials

    Open Credential Manager from the Control Panel, locate any stored credentials or Windows Credentials for the print server, and remove them. Then reconnect and re-enter credentials.

  4. 4

    Adjust Point and Print Restrictions via Registry

    Open Registry Editor, navigate to HKEY_LOCAL_MACHINE\Software\Policies\Microsoft\Windows\Printers\PointAndPrint, and ensure RestrictDriverInstallationToAdministrators is set to zero if permitted by policy.

    Modifying the Windows registry incorrectly can cause system instability. Proceed with caution.

  5. 5

    Connect via Direct TCP/IP Port

    Instead of connecting to the printer via the shared network UNC path, add a local printer and configure a standard TCP/IP port using the printer IP address.

  6. 6

    Update Drivers on the Print Server

    Ensure the print server utilizes modern Type 3 or Type 4 drivers that match the client operating system architecture.

  7. 7

    Run the Windows Printer Troubleshooter

    Open Windows Settings, navigate to Troubleshoot, and run the built in Printer troubleshooter to automatically detect and clear spooler corruption.

  8. 8

    Install Pending Windows Updates

    Check for recent Windows updates on both the client machine and the print server, as Microsoft frequently patches Point and Print communication bugs.

When to contact a professional

Call your enterprise IT administrator if your organization manages your print server. Stop right there if you lack the permissions to change registry keys and group policies, or if domain security protocols prohibit overriding Point and Print restrictions. Registry modifications risk system stability. Do not proceed if any of this applies to you.
