Only way I found to restore the print settings is to uninstall the incorrect print driver. The way to do this is download the incorrect driver again, go through the install process. When you get to the dialog box that says easy install, click on it. This should be a drop down menu and it will give the option to uninstall. This will remove the driver files. Just install the Intel driver after that.
