ABSTRACT:
A liquid ejecting device and method control the flying characteristic of liquid while enabling stable ejection of the liquid, without shortening the life of bubble producing units (heating resistors). The liquid ejecting device has heads each including liquid ejecting portions arranged in parallel which each include a liquid cell, bisected heating resistors in the liquid cell which produce bubbles in liquid in the liquid cell in response to the supply of energy, and a nozzle for ejecting the liquid in the liquid cell by using the bubbles produced by the heating resistors. The heating resistors are supplied with energy, and a difference is set between a manner of supplying energy to one heating resistor and a manner of supplying energy to the other heating resistor. Based on the difference, a flying characteristic of the liquid ejected from the nozzle is controlled.
