A printer has a sensor for detecting notches spaced along a label media fed through the printer at a reference distance, where the reference distance is selected as a multiple of a number of steps. As the label media is fed through the printer, the printer monitors the command to and/or feedback from a motor to determine an expected feed length, monitors the notches to determine an actual feed length, and compares the actual feed length to the expected feed length to determine a difference. The printer then adjusts the command to the motor to account for the difference, and therefore to minimize the difference between the actual feed length of the label media and the desired feed length of the label media.
