The ink jet printer comprises a printhead ( 22 ) movable in front of a printing medium ( 30 ) and provided with an ink cartridge ( 25 ) integral with it; the cartridge is filled with ink from a main, high capacity tank ( 35 ), which is connected at intervals to the cartridge ( 25 ) by means of a capillary element. During each connection, the capillary element ( 101 ) is brought into contact with the sponge ( 41 ) inside the cartridge, while a peristaltic pump ( 134 ) mounted integral upon the main tank provides a pressure suitable for generating a sufficient flow of ink to refill the cartridge ( 25 ) in a short time frame. To perform the refilling, the cartridge is brought at the end of its stroke into a service station ( 5 ) mounted on the body of the main tank ( 35 ), which is moved against the cartridge by means of a motor-driven linkage, controlled by a refilling management programme, in response to the signals of a cartridge ink level sensor.
