1. An image forming apparatus connectable to a peripheral unit operable to transport a recording medium, the image forming apparatus comprising:
a communication device facilitating communication with the peripheral unit; and
a controller controlling transporting the recording medium by the peripheral unit using communication from the communication device,
wherein the controller sets a plurality of transport speeds, each of which corresponds to a predetermined identification code, to the peripheral unit and specifies the transport speed by using the predetermined identification code to the peripheral unit,
wherein the controller transmits a number of transport speeds to be set to the peripheral unit before the controller transmits the transport speed to the peripheral unit, and
wherein the peripheral unit returns a size of the recording medium set on the peripheral unit responsive to the peripheral unit receiving the number of transport speeds transmitted from the controller.
