  • Publication number: 20160094729
    Abstract: An image forming apparatus in an image forming apparatus development support system includes an apparatus control section and an output section. Upon receiving virtual apparatus information from a development computer, the apparatus control section perceives the image forming apparatus as if an unattached optional device were attached to the image forming apparatus despite the fact that the unattached optional device is not attached. The apparatus control section then controls an apparatus storage section to store the virtual apparatus information as apparatus information indicating the current apparatus state. Upon receiving an instruction for outputting a report indicating the state of the image forming apparatus while the virtual apparatus information is stored in the apparatus storage section, the output section outputs the report based on the virtual apparatus information in accordance with a report outputting program.
