A technique for marking media with indicia in such a way as the media may be loaded into the printer in any orientation. These indicia marks are read by a printer for the purpose of identifying the media, determining the orientation of the media, and providing additional information about the media. The indicia encodes the necessary information for the printer to identify the media as well as additional information about the media that may be useful for the printer. In a typical embodiment, the indicia will be invisible to the human eye but machine readable. On sheets of media, indicia are placed in the margin of the media in eight corners of the page, four on the front and four on the back. The indicia are placed and orientated such that the indicia are in the same relative position and orientation to the printer regardless of the orientation in which the media is loaded into the printer. |
