When a print process command is outputted from a port terminal, an MFP displays first print information related to the print process command of the port terminal on a display unit. An outbound message is created having outbound strings including a first set of the outbound strings representing the outbound characteristics and a second set of the outbound strings representing the outbound content. A sensor array is arranged proximate the display screen to detect a touch on the display screen and to generate a set of touch position coordinates corresponding to a location of the touch.
