Hi Jim,
Download and install "Revo - Uninstaller" [ free version ] from here - click here
Run it and see if it locates your XP 412 software.
If it does - click on this and from the toolbar at the top - click on "Delete".
Use the default settings.
You may be asked if you want to delete registry settings for the XP 412.
This is OK - but if you are unsure then obviously leave this out.
Once you have removed the drivers - re-install them again from the link I gave you earlier.
Make sure that you do not have the USB lead connected to the printer when you do this.
