Abstract:
1. A data processing method, comprising: providing a first device adapted to be connected to a second device, and comprising a communicator having a first interface function defined in an asymmetric interface standard and operable to communicate at least one of a data file and a control command which causes the second device to print an image based on image data, with the second device having a second interface function defined in the asymmetric interface standard; connecting selectively either a personal computer or a printer operable to perform printing without aid of a personal computer to a single connection port of the first device, as the second device; judging whether the second device connected to the connection port is either the personal computer or the printer; causing the communicator to transmit, to the second device, an image data file containing image data and a control signal causing the second device to print an image based on the image data, in a case where it is judged that the printer is connected to the connection port; and causing the communicator to communicate a data file with the second device in a case where it is judged that the personal computer is connected to the connection port.
