To allow an image feed unit for outputting an output process instruction to an image output unit according to one-to-one direct connection to output an image from a network type image output unit. One-to-one communication means 104 is connected to an image feed unit 1 capable of being connected directly to an image output unit 6 by one-to-one correspondence. Network communication means 105 is connected to a plurality of network type image output units 3 capable of performing an output process based on an output process instruction via a network 5. Receiving means 134 receives an output process instruction from the image feed unit 1 via the one-to-one communication means 104. Transferring means 143 selects one from a plurality of the network type image output units 3, and then transmits the output process instruction received by the receiving means 134 to the selected network type image output unit 3 via the network communication means 105.
