Abstract
A method and system to align a printer for printing on a media includes detecting a left edge position and a right edge position of a calibration mark while scanning a carriage horizontally over an area holding the media, determining a horizontal coordinate position of the calibration mark according to the left and right edge positions, cross referencing a width measured between the left and right edge positions of the calibration mark with a predetermined vertical coordinate position, and adjusting a horizontal offset in a carriage direction relative to the horizontal coordinate position of the calibration mark and a vertical offset in a media advance direction relative to the vertical coordinate position of the calibration mark.
