Printing system for performing visible and invisible printing, terminal apparatus for the printing system, and non-transitory computer-executable medium for the printing system

A terminal apparatus comprising circuitry configured to:

• compressing data corresponding to an entirety of a print target image or a part of the print target image;
• generate an image of a two-dimensional code by two-dimensionally encoding the entirety of the print target image or the part of the print target image, the two-dimensional code generated 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 an image forming apparatus configured to perform visible printing and invisible printing, the print data to which the printing command is added, the transmitted print data causing the image forming apparatus 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.

A non-transitory computer-executable medium storing a program including computer readable instructions which, when executed by one or more processors of a terminal apparatus, causes the terminal apparatus to perform a method comprising:

• compressing data corresponding to an entirety of a print target image or a part of the print target image;
• generating an image of a two-dimensional code by two-dimensionally encoding the entirety of the print target image or the part of the print target image, the two-dimensional code generated based on the compressed data;
• adding 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
• transmitting, to an image forming apparatus configured to perform visible printing and invisible printing, the print data to which the printing command is added, the transmitted print data causing the image forming apparatus 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.
