An image processing apparatus is used for copying an original. A reading section reads an image of an original. An image forming section forms the image of the original on a medium. When an error detector has detected an error in the image processing apparatus, a network connecting section connects the image processing apparatus to a network so that a printer detector detects an external image forming apparatus connected to the network. Then, a selecting section selects the image forming apparatus connected to the network. The image forming apparatus is selected based on certain predetermined conditions. Then, an image transferring section transfers the image of the original to the image forming apparatus so that the image of the original is printed by the detected image forming apparatus.
