Abstract
An image forming device to which an external device is detachably attached, including an interface that is able to attach to the external device, a storage that stores multi-tier architecture software, and a computer that executes the multi-tier architecture software. The multi-tier architecture software includes a lower layer that includes an operating system that manages the external device, an upper layer that includes an application program that accesses the external device via the lower layer, and an intervening abstraction layer that hides implementation of the lower layer from the upper layer. The upper layer includes an access control program that is able to save path information to access the external device to the storage, and relays access from the application program to the external device by accessing the lower layer without going through the abstraction layer and accessing the external device using the path information.
