Printer and printer control method

摘要

A printer capable of preventing clogging the printhead nozzles due to paper dust produced from sprocket holes in continuous paper, and preventing the printhead from ejecting ink droplets except on the continuous paper, has a printhead that ejects ink droplets toward continuous paper having sprocket holes formed along both sides of the paper width; a cover member that covers the edge part of the width of the continuous paper where sprocket holes are formed in the range of the printhead in the conveyance direction of the continuous paper, and can move in the paper width direction; and a detection mechanism that detects the position of the cover member in the paper width direction.

主权项

1. A method of controlling a printer that has a printhead configured to eject ink droplets toward continuous paper, a cover member configured to cover from above a part of a width of the continuous paper and configured to move in a paper width direction, a detector configured to detect the cover member, and a controller configured to determine a position of an edge of the continuous paper in the paper width direction based on the cover member the control method comprising steps of:
detecting a position of the cover member in the paper width direction; and determining the position of an edge of the continuous paper in the paper width direction based on the detected position of the cover member in the paper width direction.
