FIELD: printing engineering, in particular, printing devices (printers) with a thermo-jet printing head.
SUBSTANCE: the cartridge has a reservoir for ink, in which a stable negative pressure is maintained. For maintaining of a stable negative pressure in the reservoir use is made of a single component fulfilling simultaneously the functions of the reservoir walls and the regulator of negative pressure in the reservoir. A bag of film material is used as such a component.
EFFECT: provided a high-quality printing due to a uniform feed of ink during the whole service life, minimized number of components for fabrication process.
