A printing system includes a terminal device and a printer device. The terminal device includes a generation module configured to generate image data, a computation module configured to compute check digit data based on the image data, and a transmission module configured to append the check digit data to the image data and transmit the image data with the check digit data appended. The printer device includes a receiving module configured to receive the image data and the check digit data from the terminal device, a decision module configured to decide whether the received check digit data is valid or not based on the received image data and the received check digit data, and a printing unit configured to print an image on a recording medium based on the received image data if the check digit data is determined to be valid. |
