An optical sensor device (10) includes an application module (12) for applying an irregular pattern of marks to a surface of a medium and an optical detector module (14). The optical detector module (14) acquires images of the applied marks and may determine an advancement speed of the medium based on the acquired images.

A printer in one example includes a thermal printhead with resistive heating elements. A motor is provided in the printer for conveying paper to the thermal printhead. A power supply is provided to supply power to the thermal printhead and the motor. A processor is configured to cause the supply of power to the motor to be paused after the supply of power to the thermal printhead exceeds a power threshold value and then to resume the supply of power to the motor after a predetermined period of time elapses after the pause of the supply of power to the motor.

A registration system for a printing device and a method for controlling the same are disclosed. For example, the registration system includes at least one sensor, omni wheels, a motor coupled to each omni wheel, a translating carriage, and a processor communicatively coupled to the at least one sensor, the motors, and the translating carriage, wherein the processor calculates a desired movement to move the omni wheels and the translating carriage based on the position of the print media.
