FIELD: jet printers.
SUBSTANCE: device has to be jet-printing head. Printing head has many drop generators reacting to excitation current and address signals; printing head is used for releasing ink. Jets printing head has first and second drop generators disposed in printing head. Any drop generator is made for reception excitation current from excitation current source. Any drop generator is made for reception of address signals from common address source. Jet printing head also has switching unit connected between common address source and any drop generator.
