Introduction
From manufacturing work orders to customer invoices and paychecks, these Hewlett
Packard LaserJet printers now output an array of critical documents. Of course, as the
importance of the documents output by these printers increases, so does the need for
greater printer security and accountability. Capella Technologie’s SecureDIMM™ is a
hardware-based solution that addresses this need.
In the event that a file can not be printed immediately due to network traffic or printer
status (for instance, “printer off-line” or “printer out of paper”), client application
output is stored or queued in print spool files on either the client system or network
print server. These spool files can be “cracked” with simple text editors making the
data vulnerable to unauthorized duplication, perusal and modification.
Application output data encryption, can minimize the effects of tampering by making
the data unviewable. Once the data leaves the host it can be encrypted and with the
Decryption Option it can be de-encrypted at the printer.
The Decryption option provides sophisticated hardware-based data decryption
capabilities that are built into the firmware on the DIMM, where they can be activated
by a special printer escape code.
Because the decryption takes place in the printer hardware just prior to the output
being generated it makes the data stream less vulnerable to unauthorized access while
still providing access to other printer enhancements such as optional printer fonts
and languages.
In the absence of a decryption escape code, the printer continues to function like any
other LaserJet printer, providing maximum investment efficiency. For maximum
security applications, however, the DIMM can be configured so that the printer will
only output encrypted data. This feature could prove useful in payroll and other
check writing applications.
In its appearance and installation, the SecureDIMM closely resembles a standard HP
LaserJet memory DIMM. Indeed, its pin configuration is analogous to a standard
DIMM, making it compatible with all recent DIMM-based HP LaserJet printers.
The SecureDIMM occupies a single memory socket, leaving any additional sockets
available for printer memory upgrades. It was engineered to offer full LaserJet
compatibility, so it can coexist with other printer personalities, including Postscript
language support. This design also offers compatibility with most standard software
applications.
Although the Capella SecureDIMM looks somewhat like a standard DIMM, in its cons-
6
truction and function it is really quite different. The Security DIMM presents two physical
and logical sides. The first is the firmware side. It is on this side that the audit code is
contained. The second side is the storage side. The DIMM also contains an optional
interface for I/O capabilities.

Installing the SecureDIMM Board
Your HP LaserJet has Dual Inline Memory Module (DIMM) slots. The Capella Technologies SecureDIMM can be installed in any of these slots. The SecureDIMM is installed
exactly like a memory DIMM module. For instructions on how to install the SecureDIMM
please reference the adding memory section of your printers HP LaserJet Printer User’s
Manual.
CAUTION:
DIMM modules can be damaged by small amounts of static electricity. Wear an antistatic
strap (or frequently touch the surface of the antistatice bag or bare metal of the printer)
when handling the board, and before installing or removing it.
WARNING:
Before installing the DIMM board turn the printer off and unplug the power cord. Hazardous voltages are present in the printer.
NOTE:
The Capella Security module is a PCL Printer Personality (firmware). A conflict may occure
if another DIMM with PCL Printer Personality is installed.

Installing the
Capella Technologies Secure Level II Driver
for Windows 2000 ®
This section outlines the installation process for the Capella Technologies Secure
Level 2 Printer Driver for the Microsoft Windows 2000 Operating System.
Important: Install the DIMM containing the Capella Technologies Secure
Level 2 Firmware in your printer before beginning the software
installation.
The software installation is performed in three phases:
1. Install the Standard HP LaserJet 4100 Drivers.
2. Install the RedMon Port Monitor and Capella Encryption Filter.
3. Install the Encrypted Printer Driver.
The remainder of this document details the driver installation process.
