Zusammenfassung:	A printing system comprises an inkjet printing head having a plurality of nozzles, and a container containing a liquid material and being in fluid communication with the head by a conduit for feeding the head with the liquid material. The printing system also comprises a pressure sensor configured to generate a signal indicative of a pressure at an outlet of the conduit, and a controller configured to control the head to dispense through the nozzles liquid material received via the conduit, and to calculate one or more jetting characteristics based on the pressure.
