Abstract: A printer is provided to improve the conveying accuracy of a Y-bar, thus improving printed image quality. The printer includes the Y-bar that extends in a first direction above a flatbed on which a medium is mounted, holds an ink droplet ejecting head unit so that the head unit is movable in the first direction, and is held so as to be movable with respect to the flatbed in a second direction perpendicular to the first direction. The printer includes a drive mechanism that conveys the Y-bar in the second direction, a drive control device that carries out a drive control of the drive mechanism, and a measuring device that directly measures an amount of movement of the Y-bar with respect to the flatbed. The drive control device corrects controlled variables of the drive mechanism based on the amount of movement of the Y-bar measured by the measuring device.

Abstract: A printer including a feeding unit configured to perform repeated feeding of a medium for a predetermined feeding distance in a predetermined feeding direction, a print head configured to print on a printing surface of the medium in a printing zone set each time the feeding unit performs a feeding of the medium for the feeding distance, and a printing pass setting unit configured to set the printing zone containing a plurality of printing passes. The printing pass setting unit sets the printing passes such that boundaries between the printing passes extend diagonally relative to a width direction of the medium that is perpendicular to the feeding direction. The printing pass setting unit can set the printing passes such that the boundaries between the printing passes extend in waveform in the width direction with oscillation of the waveform being in the feeding direction.
