Abstract: In one example in accordance with the present disclosure, a printing system is described. The printing system includes a media sensor to detect a presence of media at a particular point within the printing system. A stepper motor moves media through the printing system. A controller 1) monitors, for at least one pass of the media, a number of steps of the stepper motor to pass the media between the media sensor and a print position, 2) stores the number of steps of the stepper motor in a memory device, and 3) adjusts operation of subsequent passes of the media based on stored number of steps. A memory device of the printing system stores the number of steps of the stepper motor, for at least one pass of the media.
