ABSTRACT:
Methods and apparatus are provided for securely printing a print job on a networked printer. An application program running on a networked computer instructs the printer to generate and exchange cryptographic keys. The application program then encrypts the print job using the keys, and then communicates the encrypted print job to the printer. The printer decrypts the received print job and prints the document.
