Error 0x00000709 denotes a situation, when a user cannot configure a default printer in Windows or a different printer to one that has been already configured as default. A glitch in Windows Registry settings may cause the error to pop up or the situation where Registry prioritizes a previously assigned printer as default.

For troubleshooting printer issues such as Error 0x00000709, it is necessary to have a back up of the Windows Registry before manually modifying the settings. To take a backup, press down R key and Windows key simultaneously and key in regedit in the Run dialog box. When the dialog box of User Access Control pops up next, seeking permission to run Registry Editor as Administrator, click Yes in order to run it.

After that, click on HKEY_CURRENT_USER, expand Software folder, and then scroll down to and click Microsoft. After that, click to expand Windows NT and again choose Windows folder. Then, right-click on the REG key titled Device to the right side of the Windows Registry Editor, and choose Modify from the context menu that pops up.
