Abstract
One requirement for Airprint compatibility is that the printer “know” the size of the media loaded in the
input tray and that that information be reflected in the iOS device before sending a print job. Media size
may be determined in a number of ways. For instance, users may input media size using a user interface
(e.g., UI), such as by way of a control panel of the printer. However, printers without control panels
present a challenge. In such cases, therefore, it may become necessary to enable the auto detection of
media size. This paper proposes structures and methods to optimize a number of sensor to use for auto
detection of media size in the printer (which affects cost) to enable use of a FW algorithm to
differentiate between 4"x6" (102 mm x 152 mm) media with 4"x5" (102 mm x 127 mm) media (different
in length) to allow use of AirPrint.
