Abstract
Printing apparatus that employs a media detect switch and a linear optical detector to accurately detect the leading edge or trailing edge of a print medium to modify print data so that printing does not extend off the print medium beyond the leading edge or trailing edge. Also disclosed are techniques for using the media detect switch to control a media advance operation to position the leading edge or trailing edge of the print medium in the field of view of the linear array optical detector.
