Abstract: The system for supplying ink to an ink jet head includes a plurality of modules in a stacked construction. Several ink jet printing modules are supplied jointly through a flexible connection, via an ink hose extending between the ink jet head and an ink tank. One common adapter connects to an inlet connection neck for each module. The inlet connection necks communicate fluidically with a common supply conduit present in tabs, which are formed on the faces of the printing modules, and which extend parallel to a side edge of the modules. The common adapter has a pressure equalization diaphragm and a filter, and it is mounted resiliently and rubber-elastically on the inlet connection necks. The pressure fluctuations are thereby balanced out, drafts of air in individual jets are limited, and soiling of the ink conduits by foreign particles is prevented.

Abstract: The invention concerns a postage meter with an electrothermal printing device by means of which value indications and/or graphics are printed onto a postage item moved past it at a predetermined speed by the transfer of color particles in a graphic forming distribution from a carrier web (114), which carrier web is heated by means of a thermal print head in correspondence to the graphic forming distribution and is driven past the printing device, with a counterpressure element (116) standing oppositely to the thermal print head (110). As the counterpressure element a counterpressure roll (116) is provided which is movable in a direction perpendicular to the printing surface, which counterpressure roll is so yieldingly supported on a shaft arranged parallel to the printing ledge (112) of the thermal print head (110) that its contact face with the postage item can take on different angles to the printing ledge (112) in a plane containing the printing ledge (112) and the shaft (130).
