When a user uses an image processing device, the image processing device accesses a private PC of the user connected to a network to request acquisition of environmental information. A printer driver in the private PC collects various settings (including desktop theme, application settings, and device driver settings) from within the private PC. The settings are transmitted to the image processing device. The image processing device, based on the acquired setting information, changes the panel display, application settings, and others. This simplifies setting of the image processing device.
