Abstract:
1. A printing apparatus comprising: a plurality of print heads; a moving member that moves along a main-scanning direction and that is provided with the plurality of print heads; a roll paper; a feed mechanism that feeds the roll paper; a drive member that is connected to the moving member at a connecting section and that drives the moving member along the main-scanning direction; a controller that makes a predetermined print head, among the plurality of print heads, eject ink to form dots for correcting a feed amount by which the feed mechanism feeds the roll paper, while moving the moving member, the predetermined print head being a print head other than the print head that is the furthest away from the connecting section in a direction perpendicular to the main-scanning direction, among the plurality of print heads; a support member that support the roll paper; a suction member that sucks the roll paper toward the support member; and a first detector that detects a force by which the suction member sucks the roll paper; wherein whether or not to form, on the roll paper, the dots for correcting the feed amount by which the feed mechanism feeds the roll paper is determined according an output value of the first detector.
