S3: and acquiring an original image, and carrying out binarization on the original image to obtain an image to be printed.
Referring to fig. 3, the step S3 of binarizing the original image to obtain an image to be printed includes the following steps S31 to S34:
s31: setting a pixel value threshold;
s32: taking each pixel point of which the pixel value is greater than or equal to the pixel value threshold value in the original image as a target pixel point;
s33: taking each pixel point in the original image, of which the pixel value is smaller than the pixel value threshold value, as a non-target pixel point;
s34: and setting the pixel value of each target pixel point to be 1, and setting the pixel value of each non-target pixel point to be 0 to obtain the image to be printed.
