Abstract:
An information processing system which makes it possible to enable the effective use of an optional function (surplus optional function) remaining in an unusable state. When one printing apparatus has optional function data (license or an application program) stored therein for execution of an optional function, without a required optional device mounted thereon, and another printing apparatus has the optional device mounted thereon without the optional function data, the optional function data is transferred from the one printing apparatus to the other printing apparatus. Upon reception of the optional function data, the optional function data is stored in a storage device of the printing apparatus. When the optional function data stored in the storage device, and the optional device is mounted, the optional function is caused to be executed.
