A portable hand-held manually operated dry printing apparatus comprises a frame structure, a ribbon holder mounted on the top portion of the frame structure, a dry printing unit mounted on the lower portion of the frame structure and comprising a die member and a heating device for heating the die member, two handles respectively mounted on the two sides of the frame structure, and a ribbon guiding system for guiding the ribbon from the ribbon holder along a path extending between the die member and the surface on which dry printing is performed. Each handle is spaced apart from a portion of the dry printing apparatus heated by the heating device to define an air passage between the handle and the surrounding heated portion, to thereby ventilate an inner face of the handle and prevent this handle from being heated. The ribbon guiding system comprises a generally rectangular bottom plate defining a window and two end notches for guiding the ribbon in front of the window. This generally rectangular bottom plate is mounted to the frame structure through a pair of spring-biased sliding posts sliding on the frame structure against the force exerted by helical springs to apply the die member to the ribbon through the window and thereby transfer material from the ribbon to the surface on which dry printing is performed. The force exerted by the spring members returning the sliding posts and therefore the die member to their initial rest position after the dry printing operation is completed.
