Abstract:
A media content printing method that includes storing encrypted media content data representing media content in a computing device, generating a file of print commands that include the encrypted media content data non-encrypted commands for printing the media content based on the encrypted media content data, and sending the file of print commands to an intermediate device that stores a cryptographic key. The method further includes sending the non-encrypted commands to a printing device, determining if the media content is authorized to be printed, and decrypting the encrypted media content data in the intermediate electronic device that corresponds to the authorized media content to produce decrypted media content data. The decrypted media content data is sent to the printing device for printing the media content based on the non-encrypted commands and the decrypted media content.
