Overview
The Lexmark PrintCryption
TM
is an option for the Lexmark printers that enable
the transfer and printing of encrypted print jobs. This new Lexmark technology
offers a level of security that is the first of its kind in the printing industry. With
the PrintCryption module installed, the printer is capable of decrypting print jobs
encrypted with the AES (FIPS 197) algorithm. The Lexmark PrintCryption
TM
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. This new level of printing security is ideal for industries that commonly
handle sensitive or personal information, such as financial institutions,
government agencies, and healthcare organizations.
Module Specification
The PrintCryption
TM
module (firmware version 1.3.1) is a firmware module
composed of three binaries, and it is installed in Lexmark printers using a
Downloaded Emulator Card (DLE), a serial interface PCB board that plugs into
the printer. The DLE card is shown in Figure 1.

Per FIPS PUB 140-2, the cryptographic module is classified as multi-chip
standalone cryptographic module. The module meets overall level 1 FIPS 140-2
requirements, as detailed in Table 1.
