  • Patent number: 6829707
    Abstract: A method and system for downloading encrypted double-byte font scripts to a print server. A communication element is interposed between a data processing system and a print server, where the print server does not support a bi-directional communication protocol utilized by the data processing system to download encrypted double-byte font scripts. The communication element supports data transmissions in both the bi-directional communication protocol and with the print server. To download a double-byte font script, the data processing system transmits a request to the print server through the communication element for an identifier from the print server. The print server transmits the identifier to the data processing system through the communication element. A decryption key for the double-byte font script is produced by the data processing system utilizing the identifier and downloaded with the encrypted double-byte font script to the print server through the communication element.
