A method of an embodiment of the invention determines whether at least a portion of an image to be formed on a media sheet on a swath-by-swath basis by an image-formation mechanism includes one or more bar codes having a height that is less than a height of a swath of the image-formation mechanism. The mechanism adjusts the swath of the image-formation mechanism so that the bar codes are formed as part of the image on the media sheet within a single swath by the image-formation mechanism.
