A code printing apparatus includes a speech input unit for inputting speech information, a code output unit for printing the speech information input by the speech input unit on a medium as an optically readable code pattern image, and a speech code printing control unit for controlling the code output unit to print the speech information input by the speech input unit on the medium as a corresponding code pattern image on the basis of the input operation at an operation unit controlled by the user. The user can thus easily achieve a function of printing speech data or the like as an optically readable code.
