When the length of a print area in a print tape is designated and an instruction to print a symbol image of a two-dimensional code and character information is given, a printing apparatus sets the print size of the symbol image of the two-dimensional code to a predetermined print size defined as the initial setting, but changes the print attributes of the character information from the initial values to adjust the length of the character string, so that the character information can be printed together with the symbol image of the two-dimensional code within the print area in the print tape, that has the designated length. The printing apparatus prints the character information whose print size is adjusted and the symbol image of the two-dimensional code maintained at the predetermined print size, in a serial arrangement, in a range of the print tape having the designated length.
