<p>The inventive ink-jet printing head comprises a large number of cells. Each cell in its turn comprises an ink reservoir, a dosing unit whose body is made of silicium monocrystal and provided with a base and a lid. A channel connecting to the ink reservoir is embodied in the base. An output channel of the dosing unit is embodied in the base and the lid, and provided with an output nozzle oriented towards a recording medium at the end thereof. Said head also comprises at least one resistance heater arranged in the dosing unit and electrically connected to a power supply by means of a control unit. The resistance heater is arranged in the output channel close to the output nozzle. The ends of the resistance heater are fixed to the base on the opposite walls of the output channel of the dosing unit. A plane on which the resistance heater is arranged passes through the longitudinal axis of the output channel.</p> |
