Printing medium detection device and printing equipment

The utility model provides a printing medium detection device and printing equipment. The printing medium detection device comprises a signal filter circuit, a sensor driving circuit and a mark sensor, the input end of the signal filter circuit is electrically connected with the first end of the marking sensor, and the output end is electrically connected with the input end of the sensor driving circuit; the signal filter circuit is used for receiving a pulse width modulation signal sent by the marking sensor and processing the pulse width modulation signal to obtain a target direct-current voltage signal; the output end of the sensor driving circuit is electrically connected with the second end of the marking sensor; the sensor driving circuit is used for receiving the target direct-current voltage signal sent by the signal filtering circuit and driving the marking sensor to detect the label position of the printing medium; wherein the sensitivity degree of the marking sensor is related to the voltage value
