Data processing apparatus for controlling operation of a peripheral device, e.g., a printer. The data processing apparatus is adaptable to different operation environments of a peripheral device, e.g., geographic difference. Control means of the peripheral device stores a local ID indicative of environment data e.g., a country where the device is used. The local ID is acquired, and then a resource file corresponding to the local ID is acquired. The resource file stores control data of the peripheral device, which changes in correspondence with environment data. Based on the control data, setting of the peripheral device is performed. The local ID is stored so that the local ID can be used in the subsequent processing.
