1. A printing system comprising:
an image forming apparatus configured to perform visible printing and invisible printing; and
a terminal apparatus, the terminal apparatus including first circuitry configured to,
generate an image of a two-dimensional code by two-dimensionally encoding an entirety of a print target image or a part of the print target image, the generating the image of the two-dimensional code including,
compressing data corresponding to the entirety of the print target image or the part of the print target image, and
generating the two-dimensional code based on the compressed data;
add a printing command to print data generated based on the print target image, the printing command including instructions to the image forming apparatus to invisibly print the generated image of the two-dimensional code, and
transmit, to the image forming apparatus, the print data to which the printing command is added; and
the image forming apparatus includes second circuitry configured to,
visibly print the print target image based on the transmitted print data, and
invisibly print the image of the two-dimensional code according to the printing command, the invisibly printed image of the two-dimensional code printed on a same print sheet as a print sheet on which the print target image is visibly printed.
