A printing apparatus communicates with a weight measuring apparatus and a mobile terminal. The weight measuring apparatus transmits measuring data of weight of a measurement object, and the mobile terminal transmits a data acquisition command requesting for transmission of the measuring data. The printing apparatus includes a head to execute printing on a print medium, and a controller. The controller is configured to: receive the data acquisition command from the mobile terminal; change a state of the printer from an instruction waiting state to a data reception waiting state; receive a second measuring data transmitted from the weight measuring apparatus; transmit the second measuring data to the mobile terminal; receive a print command corresponding to the second measuring data from the mobile terminal; and control the head based on the received print command to perform the printing, on the print medium, corresponding to the second measuring data.
