ABSTRACT:
An interface apparatus includes a USB interface portion which makes communication with an external first device via a USB cable, a parallel interface portion which makes communication with an external second device via a parallel cable, and a control portion which, after a processing command signal has been received from the first device via the USB interface, when a signal state of the parallel interface portion is detected, and then, it is determined that the second device connected to the parallel interface portion enters a power saving mode, generates a switch signal for switching the current power saving mode to a normal mode to supply the switch signal to the second device via the parallel interface portion, and after it has been detected that the second device has been switched into the normal mode, controls the processing command signal so as to be supplied to the second device via the parallel interface portion.
