A pivotable duplexing unit is attached to the wall of a printer using a hinge having an axis that is substantially perpendicular to the base. A latch and catch holds the pivotable duplexing unit in a closed position relative to the wall of the printing apparatus. The wall includes a support member for the hinge, and the pivotable duplexing unit further includes a pin for pivoting in a support member of the hinge. The support member includes a bearing surface that is substantially parallel to the base. The pin member includes an end that makes pivotable contact with the bearing surface.
