Overlying the screen on the side of the screen external to the interior chamber is a connection including a tubular element having an inlet end with a porous sealing element for connection with an ink cartridge. A sealing ring surrounds the inlet end. The connection further includes a second flow passage for conducting ink from the inlet end through the interior of the tubular element to the screen external to the interior chamber.
