Thank you for posting in Q&A forum.
To resolve the error code 0x00000709, you must first change the printer name in Registry Editor and then change the RPC connection settings policy. If these steps do not resolve the issue, you can run the printer troubleshooter, change the printer preferences settings, and uninstall the problematic update.
