Printing apparatus, printing apparatus control method, printing apparatus control program, and printing system

A printing apparatus includes: a tag information reading/writing unit which reads information from an IC tag attached to or embedded in a predetermined location of a print medium and writes information to the IC tag through wireless communication with the IC tag and which reads layout information, which defines at least a location of a printable area on the print medium, from the IC tag; a record data inputting unit which inputs record data representing contents recorded on the print medium; and a printing control unit which performs a printing process on the print medium on the basis of print target data in which a print location of the contents represented by the record data is determined on the basis of the layout information and which updates the layout information on the basis of information directly or indirectly representing a printed area in the print medium subjected to the printing process and allows the tag information reading/writing unit to write the layout information subjected to the updating process to the IC tag.
