Abstract
The present application discloses a method for erasing printing information of a YMC ribbon, a printing device and related equipment. The method comprises the following steps: after completing the printing of portrait data using a whole roll of YMC ribbon, rotating and resetting the whole roll of YMC ribbon having a plurality of ribbon areas with residual portrait information, determining face information from the portrait information for each ribbon area in the YMC ribbon, and erasing and printing the face information. The present application can complete the destruction of the YMC ribbon without increasing the investment in destruction equipment, thereby effectively avoiding the leakage of user information. Moreover, the present application only performs erasing and printing on the face information in the identified face area, thereby effectively avoiding the leakage of user personal information, further improving the efficiency of erasing and printing, and reducing the use time of the print head during the erasing and printing process, thereby extending the service life of the print head.
