Abstract: Medium handling apparatuses and methods of media handling, both for use in printing devices, are disclosed herein. An example of a medium handling apparatus includes a first transport roller to convey a medium and a first drive mechanism to rotate the first transport roller at a first rate. This example of the medium handling apparatus additionally includes a second transport roller to convey the medium and a second drive mechanism to rotate the second transport roller at a second rate. This example of the medium handling apparatus further includes a coupling assembly to disengage the second transport roller from the second drive mechanism to allow the medium to rotate the second transport roller at the first rate.
