Abstract

A method and system of selectively and securely enabling an added or premium functionality in a printer can be created by transmitting or inputting to the printer an electronic key correlated to the unique serial number stored in that printer. In this way, the key used to activate an added or premium functionality in a particular printer cannot be used to activate the same functionality in any other printer. This prevents the unauthorized activation of added or premium functions in other printers.
