Disclosed is a liquid emitting apparatus for emitting a liquid pressurized by a pressure generated by a pressure generating element is emitted as liquid droplets onto a support. A controller (68) controls an emission controller (63) so that the current value of the pulse current supplied to a heating resistor (42a) will have a current value difference within ±10% with respect to the current value of the pulse current supplied to a heating resistor (42b). By so doing, variations in the position of deposition of an ink droplet i emitted with variable emitting directions may be suppressed to enable printing to a high-quality image in which deterioration in the image quality variations ascribable to color time variations or white streaks is prohibited.
