1. A printer, comprising:
a plurality of sensors positioned within a print path before a printhead location, said sensors generating a signal indicative of a highest point of incoming media relative to a reference surface;
a control system in communication with said sensors that, in response to receiving said sensor signals, determines when the height of the incoming media poses a collision risk to one or more portions of the printer at or near the printhead location or a damage risk to the printer;
said control system generating a signal that stops operation of the printer when the height of said incoming media poses the collision risk to the one or more portions of the printer or the damage risk to the printer;
said control system, in response to receiving said sensor signals, determining that the height of the incoming media does not pose the collision risk to the one or more portions of the printer or the damage risk to the printer;
said control system, in response to receiving said sensor signals, determining that the height of the incoming media does not allow acceptable printing of the media; and
said control system generating a signal that rejects the media after the media is passed through the printer without being printed and without stopping or slowing down printer operation.
