    摘要: A method and system for controlling access to features on an electronic device, such as a printer, is disclosed. The electronic device is shipped with multiple software features, but one or more of the features may be disabled. According to aspects of the present invention, when a customer subsequently licenses or purchases one of the disabled features, the feature is enabled as follows. A key corresponding to the disabled feature is stored on a portable storage device. When the portable storage device is inserted into the electronic device, the key is customized based on device-specific information of the electronic device, thereby reducing a possibility that the key can be copied and used for enabling the feature on more than one device. The customized key is then used to enable the feature in the electronic device.
