A method and apparatus for printing user data to a form document. A scanner scans the form document at low resolution and sends document data to the computer system. User data to be printed on the form document is input into the computer system and displayed as a user data image to be printed onto the form. The scanned document data is used to create a scanned document image. The scanned document image and the user data image are overlaid on the display to indicate to the user how the user data would print onto the hard copy of the scanned document. The scanned document image is aligned with the user data image manually or automatically. The aligned user data image is then printed directly to the scanned document using a printer.
