A two-dimensional code printing apparatus includes a computer device and a tape printer. A print frame is arranged on a label making work area on an edit display screen displayed on the computer device. A user inputs a text into a text box arranged on the print frame, and then highlights the text to be coded in a two-dimensional code by a mouse, and then one-clicks a two-dimensional code button. Herewith, the text and the two-dimensional code are displayed on the text box. If the user clicks a print button, a label on which both the text and the two-dimensional code printed is printed.
