Description
The Lexmark PrintCryption Card is an option for the Lexmark T, C, W, and X series of output devices that enables the printing of host encrypted data. With this option installed, the printer is capable of decrypting print jobs encrypted with the AES algorithm. The Lexmark PrintCryption Card analyses the encrypted data stream, determines if the correct key was used to encrypt the data, decrypts the data and allows the confidential document to be printed.
