Zusammenfassung:A system (10) for printing at least one image on a partially-printed medium (50). The system (10) includes a print detector (20) that is adapted to scan the partially-printed medium (50) so as to form scan data (24), and a controller (30) coupled to the print detector (20) that is adapted to analyze the scan data (24) so as to identify at least one unprinted region (54,55) on the medium (50). A print engine (40) coupled to the controller (30) is adapted to print one or more of the images in the unprinted region or regions (54,55).
