A programmable feature such as a software upgrade, updated print driver, new process, etc. is remotely delivered to an output device, such as a printer. First, the customer tenders payment for the feature. Next, the customer is provided with a coupon. The customer subsequently redeems the coupon and receives the requested feature in the form of a feature key in response to redeeming the coupon. The customer uses the feature key to install the feature on the output device. The feature key may be a print job that contains encrypted text. Security measures may be provided to ensure that the coupon and feature key are valid, such as requiring the customer to use a pre-designated decryption key on the feature key before the feature is installed on the output device.
