FIELD: engineering of stream printing devices containing printing head assembly, receiving signals for activating drop generators for selective discharge of ink.
SUBSTANCE: device for controlling operation of drop generators is made so, that only one of them is enabled at one time moment. Device for controlling operation of drop generators is made with possible generation of signal of address and first resolution signal before excitation current for first drop generator and second resolution signal before excitation current for second drop generator.
EFFECT: prevented cross interferences on liquid during simultaneous discharge of drops from closely positioned drop generators.
