1. A printing apparatus comprising:
a platen to hold a media thereon, the media moveable along a media path direction;
a displacement mechanism to move the media over the platen and along the media path direction;
a media advancement sensor;
a controller to:
determine a media advancement prediction based on an operational parameter of the displacement mechanism;
determine a read media advancement corresponding to the media advancement prediction;
determine a sensor reading failure based on the media advancement prediction and the read media advancement;
determine that the media advanced a distance corresponding to the media advancement prediction if the sensor reading failure is detected;
determine that the media advanced a distance corresponding to the read media advancement if the sensor reading failure is not detected; and
adjust the position of the media by controlling the displacement mechanism to move the media based on the determined media advanced distance.
