Migration Manager's sin qua none is that we do not migrate things that can break the user experience. Additionally, many users collect lists of printers over the years, plus software virtual printers that are not connected to hardware. Many of these printers are no longer in use.
What we do accomplish is to capture the local printer identities and migrate them to the new desktop. An identity is a 'shortcut' that resides on the desktop. Click on the shortcut and the correct printer driver will be installed for that desktop based upon the printers the user needs at the current time.
