A liquid ejecting apparatus comprising: a liquid ejecting head having a first nozzle row that ejects a first liquid; a first tank (11_1) that stores the first liquid to be supplied to the first nozzle row; a first supply flow path (SJ_1) for supplying the first liquid to the first nozzle row from the first tank; a first on-off valve provided in an intermediate portion of the first supply flow path and configured to open and close the first supply flow path; a first pressurizing mechanism (13_1) configured to pressurize an inside of the first tank; and a first atmospheric opening valve (15_1) configured to open and close the inside of the first tank to be open to the atmosphere, wherein in a closed state of the first on-off valve, the first pressurizing mechanism is driven to set a pressure inside the first tank to a predetermined positive pressure, and thereafter, the first on-off valve is brought into an open state to perform a discharge process of discharging the first liquid from the first nozzle row, in the discharge process, the first on-off valve is switched from the open state to the closed state at a timing at which the first liquid is being continuously discharged from the first nozzle row, in the discharge process, the inside of the first tank is pressurized to the predetermined positive pressure by driving the first pressurizing mechanism in a closed state of the first atmospheric opening valve, in the discharge process, the first pressurizing mechanism is stopped before the first on-off valve is switched from the closed state to the open state, and in the discharge process, during a period from a timing that the driving of the first pressurizing mechanism is stopped to a timing that the first on-off valve is switched from the closed state to the open state, the first atmospheric opening valve is in the closed state and the driving of the first pressurizing mechanism is stopped. a liquid ejecting head having a first nozzle row that ejects a first liquid; a first tank (11_1) that stores the first liquid to be supplied to the first nozzle row; a first supply flow path (SJ_1) for supplying the first liquid to the first nozzle row from the first tank; a first on-off valve provided in an intermediate portion of the first supply flow path and configured to open and close the first supply flow path; a first pressurizing mechanism (13_1) configured to pressurize an inside of the first tank; and a first atmospheric opening valve (15_1) configured to open and close the inside of the first tank to be open to the atmosphere, wherein in a closed state of the first on-off valve, the first pressurizing mechanism is driven to set a pressure inside the first tank to a predetermined positive pressure, and thereafter, the first on-off valve is brought into an open state to perform a discharge process of discharging the first liquid from the first nozzle row, in the discharge process, the first on-off valve is switched from the open state to the closed state at a timing at which the first liquid is being continuously discharged from the first nozzle row, in the discharge process, the inside of the first tank is pressurized to the predetermined positive pressure by driving the first pressurizing mechanism in a closed state of the first atmospheric opening valve, in the discharge process, the first pressurizing mechanism is stopped before the first on-off valve is switched from the closed state to the open state, and in the discharge process, during a period from a timing that the driving of the first pressurizing mechanism is stopped to a timing that the first on-off valve is switched from the closed state to the open state, the first atmospheric opening valve is in the closed state and the driving of the first pressurizing mechanism is stopped.
