A liquid ejecting head has a head face on which nozzles adapted to eject liquid toward a first face of a target medium are arranged. The liquid ejecting head is adapted to move in a first direction. A conveyance guide member is adapted to support a second face of the target medium so that a distance between the head face and the first face of the target medium is made to be a prescribed value. The conveyance guide member includes a plurality of ribs arrayed in the first direction at a fixed pitch and extending in a second direction perpendicular to the first direction. A medium conveyer is adapted to convey the target medium in a second direction while causing the second face of the target medium to be abutted against the conveyance guide member. A controller is operable to cause the liquid ejecting head to complete liquid ejection toward a leading end portion of the target medium while the leading end portion is located at a region in which an abutment force generated by the medium conveyer becomes maximum.

A printing method comprises the steps of: in a first movement, moving a print head to form dots on a medium at aperiodic intervals in a moving direction of the print head, wherein the print head includes N pieces of nozzles arranged at a constant pitch in a direction that intersects with the moving direction, wherein the N pieces of nozzles are for forming N dots of a same color, and wherein N is an integer of at least two; in second through M-th movements, moving the print head to form, on the medium, the rest of the dots that were not formed in the first movement, wherein M is an integer of at least two; and repeating the first through M-th movements to print information on the medium.
