Abstract: The invention relates to a method for printing on a media object supported by a flat bed of a printer, the printer comprising a print head and a camera above the flat bed, the method comprising the steps of detecting a media object on the flat bed surface of the printer by means of a digital camera image captured by the camera, deriving camera coordinates of the media object in the digital camera image, applying a direct transformation from the camera coordinates into print head coordinates of the media object without using coordinates of the flat bed surface, and printing a digital target image on the media object by ejecting recording material on the media object from the print head, the print head controlled according to the print head coordinates appropriate for the media object.
