A valve member 24 forms the control member 16 and co-operates with a valve seat 25 arranged in the discharge path 13. Each of the elongated prisms is formed by a top end flat face located at the top end of the elongated prism and having an inclination angle of 1 to 50 degrees, a first prism face located at one side of the flat face, and a second prism face at the other side. The supply and recovery tanks are adapted to be selectively placed in the first and second external pockets, thereby placing the supply tank outlet in fluid communication with the fluid deposition system, the recovery tank inlet in fluid communication with the nozzle outlet, and the recovery tank outlet in fluid communication with the vacuum source inlet. An encoding type for content transferred over the network flow is determined based on the profile and the particular payload identification number.
