Claim:
An ink-jet printer configured to perform printing on a sheet-shaped printing medium, comprising: an ink supply portion through which an ink stored in an ink tank is supplied; a transport mechanism configured to transport the printing medium in a predetermined transport direction; an ink-jet head which is arranged to face one surface of the printing medium transported by the transport mechanism and in which a nozzle for jetting ink droplets of the ink supplied from the ink tank toward the printing medium is formed; an inverting mechanism configured to invert the printing medium; and a controller configured to control the ink-jet head to perform an ordinary jetting operation and a marking jetting operation, the ordinary jetting operation being an operation in which the ink droplets are jetted toward an area of the printing medium, different from an edge portion of the printing medium, and the marking jetting operation being an operation in which the ink droplets are jetted toward a part of the edge portion of the printing medium, wherein the controller is configured to control the ink-jet head and the inverting mechanism such that only the ordinary jetting operation is performed on the one surface of the printing medium without performing the marking jetting operation, and the marking jetting operation is performed on the other surface of the printing medium after inverting the printing medium with the inverting mechanism.
