A bar coded or user marked document is moved along a first transport path, where it is read. A portion of the document is situated in a curved retaining section. If validated, the document is moved completely into the retaining section and then into a second transport path, past a head for imprinting bar codes and text, to an output hopper. If invalid, the document is returned along a portion of the first transport path, along a reject transport path, to a hopper designated for this purpose. Blank documents may be fed from an internal stack into the second transport path for printing and then to an output hopper. First, second, and third frame sections define the first and second transport paths and are pivotally interconnected. Correspondingly curved portions of the first and second frame sections define the retaining section. The first frame section is mounted to the second frame section and can be pivoted relative thereto to provide access to the first path. The first and second frame sections can be pivoted as a unit relative to the third frame section to provide access to the second path.
