ABSTRACT:
The developing solution is carried in a special print tray which holds the print paper on a first planar surface which is above the surface of the developing fluid when the cover is open. When the cover is closed a displacement member forces fluid over the print paper and against a planar transparent second surface which is parallel and spaced from the first surface.
