A communication system includes a printing unit, an image scanning unit, an accessing system connectable to a web page. The printing unit prints out the web page on a first recording medium. When the web page includes an input field and the data input in the input field is to be transmitted to a predetermined destination, the printing unit prints out an image having a fill-in area to be filled in by the user, and a destination area indicating the destination, on a second recording medium. The communication system includes a scan controller that controls the scanning unit to scan the second recording medium to capture an image thereof, a recognition system that recognizes contents written in the fill-in area and the destination area based on the scanned image, and a data transmitting system that transmits contents extracted from the fill-in area to the destination extracted from the destination area.
