Apparatuses useful in printing, fixing devices and methods of stripping media from surfaces in apparatuses useful in printing are provided. An exemplary embodiment of an apparatus useful in printing includes a first member including a first surface; at least one heating element for heating the first surface of the first member; a second member including a second surface forming a nip with the first surface, the nip including an inlet end at which a substrate enters the nip and an outlet end at which the substrate exits from the nip; and an air knife disposed downstream from the outlet end of the nip and extending along an axial direction of the first member, the air knife including a first end, a second end opposite to the first end and a plurality of axially-spaced nozzles disposed between the first end and second end; and at least one gas inlet through which gas is supplied to the air knife. The nozzles are oriented to eject the gas toward the first surface downstream from the outlet end of the nip to facilitate stripping of the substrate from the first surface. The air knife has a configuration and is positioned proximate to the nip such that the substrate does not contact the air knife after exiting the outlet end of the nip when the nozzle gas ejection is ON or OFF.
