Abstract
An inkjet printer includes: an inkjet head having a nozzle row in which nozzles configured to eject ink are arranged, the inkjet head being configured to perform printing by ejecting ink from the nozzles in a state where a row direction of the nozzles in the nozzle row is a non-horizontal direction; an ink tank configured to receive a pressure for delivering ink to the inkjet head or for recovering ink from the inkjet head; and an ink path connecting the ink tank with the inkjet head. The printing is performed in a state where a parameter related to a flow path resistance of the ink path is set such that a nozzle pressure of each of the nozzles at a time of printing is within a prescribed range enabling ink to be stably ejected and ink flows at a flow rate required for the inkjet head.
