Abstract: A printer is disclosed. The printer has a media control system to control the tension in media loaded in a paper path in the printer. A motor in the media control system is characterized to determine a plurality of motor characteristics. The media control system uses the motor characteristics to adjust the control signal to the motor.

Abstract: In some examples, a method includes capturing an image of a light projection across a print substrate and a background surface beside the background surface. The method may also include identifying a break point in the image where a gap in the light projection occurs and determining a thickness of the print substrate, an edge location of the print substrate, or both, using the break point in the image.
