4. Security Concepts explanation
3.1
Secure File Erase
Secure File Erase is a feature that manages how files are deleted from the printer’s hard disk.
There are three security modes to the Secure Files Erase feature. These settings can be changed via Web JetAdmin.

Non-Secure Fast Erase: In this mode, all file pointers to the data (table indexes) are erased. Temporary
data remains on the Hard Disk Drive until the disk space it occupies is needed for another purpose, and is
then overwritten. This is the fastest mode of operation and is the default for all printers.

Secure Fast Erase: In this mode of operation, file pointers are erased and the disk space where the
temporary job was stored is also overwritten with a fixed character pattern. This mode of operation is
slower than Non-Secure Fast Erase, but all data is overwritten.

Secure Sanitizing Erase: In this mode of operation, file pointers are erased and the disk space where the
temporary job was stored is repeatedly overwritten using an algorithm that prevents any residual data.
This mode of operation may affect product performance. The Secure Sanitizing Erase mode of operation
meets the US Department of Defense 5220.22-M requirements for clearing and sanitization of disk
media. When the Secure Sanitizing Erase feature is enabled, all temporary files that might contain
sensitive data are erased with this method. No temporary files are left after a job has been completed
(scan, copy, or print).
Furthermore, if you do not want to store jobs in the printer, you can set the number of jobs to be stored in the printer’s
queue to 0. To configure this setting perform the following steps:

Go to the printer’s front panel,

Select the “setup” menu.

Select “job management setup.”
For further information, refer to the printer’s user manual, as the actual menu options may differ for a specific printer.
The following is an example of how to change the ‘Secure File Erase’ setting for the HP Designjet T1100 printer.
10
HP Designjet Printer Series
3.2
Security Settings
Secure Disk Erase
In either of the two secure methods described above (Secure Fast Erase and Secure Sanitizing Erase), there is also the
option to sanitize the whole disk. The sanitizing method removes any user data in a secure manner, so that the device
can safely be moved from a secure location to an unsecure location. All disk erasing will be carried out via the same
level of security erase.
This setting can only be used via Web JetAdmin or the Front Panel “Service menu”, which is only accessible with the
help of an HP Support representative.

11
HP Web JetAdmin access: The user interface that manages the Secure File Erase and Secure Disk Erase
functionality is the HP Web JetAdmin. This is the same functionality that is used in the Web JetAdmin
device plug-ins for LaserJet printers, which enables you to set the same global options across your fleet
of HP LaserJets and HP Designjets. The following example shows how to configure the
HP Designjet T2300 using the Web JetAdmin. Note that in the Web JetAdmin this option is called
“Secure Storage Erase”.
HP Designjet Printer Series

Security Settings
Printer Front Panel access: Once you have entered into the “Service Menu” with the help of an HP
Support representative, you can perform the Secure Disk Erase using the same 3 options that you have in
Web JetAdmin. Note that the name of the feature in the front panel is Disk Wipe DoD 5220.220M, and the
three options are called “Insecure Mode”, “1-pass mode” and “5-pass mode”.
Before you start the erase operation, you must first select the security level (sometimes referred to as sanity level).
The printer will then warn you that the erase operation is a process which deletes all data and takes a long time. Once
you accept, the printer will begin the process, and displays a progress bar until complete. All data will be wiped using
the selected method, and the printer’s firmware will be restored to the latest version installed before this operation.
The following screens show how to perform a secure hard disk erase on the HP Designjet T2300 printer.

Security Settings
Control Panel Access Lock
The control panel access lock is a feature intended for IT administrators, which enables them to lock the device’s
control panel by using either the HP Web JetAdmin or the printer’s Embedded Web Server (depending on the printer
model). This feature prevents unauthorized users from accessing the control panel and changing the printer’s
settings. Administrators can specify the level of access as follows:

Unlock

Minimum lock

Moderate lock

Intermediate lock

Maximum lock
This option can be enabled from the HP Web JetAdmin as shown below:
This option can be enabled from the T1200 Embedded Web server as shown below:


Maximum Lock – This option denies access to all options.

Intermediate Lock – This option denies access to the paper and ink supply handling options,
maintenance options and demo prints as well as the options locked by Moderate Lock. Only viewing
printer and supply information is allowed.

Moderate Lock – This option denies access to all printer settings, the job queue, information and service
prints and the printer log, as well as the options locked by Minimum Lock. For ePrinters, the setting also
locks access to these 5 security features:


Disable USB drive

Disable firmware update through USB

Disable direct print using ePrint&Share

Disable ePrint connectivity

Disable internet connection
Minimum Lock – This option denies access to the Reset options, Enable/Disable connectivity options and
the Service Menu.
Note: When the Moderate or Maximum locks are set, you will not able to load/unload paper or replace printheads/ink
cartridges without first unlocking the front panel, and so these options should only be set in specific circumstances
where the implications are known and understood.
When the Control Panel is locked, the applicable menus show a ‘lock’ symbol in the front panel. If a user attempts to
access a “locked” menu entry, a warning message is displayed.
3.3.1 Deadlock: Front Panel locked + EWS password forgotten
Under certain circumstances, a printer might become inaccessible if the control panel has been locked and the
administrator has lost the password needed to unlock it. This could happen if the front panel is locked through the
printer’s Embedded Web Server and the Administrative password for the EWS is lost. In this situation, it would not be
possible to unlock the front panel from the Embedded Web Server and it would not be possible to reset the Embedded
Web Server from the front panel.
With HP Designjet Printers there is a menu option that users can access with the guidance of Customer Support
agents. If you encounter any problems related to deadlock, then you should contact HP Support as soon as possible.

3.4
Security Settings
Embedded Web Server (EWS) multilevel access
The Embedded Web Server is a powerful tool which enables direct management of a device such as an HP LaserJet
printer or an HP Designjet printer. With no security in place, however, this tool also has the potential to have a
negative effect on many features, as they can be configured using just a web browser and knowledge of the IP address
of to the printer. To solve this situation we have implemented two levels of access to our compatible HP Designjet
printers.
The Security page enables users to:

Restrict access to the printer by setting an administrator user account.

Define two levels of access: Administrator and Guest.
If the two levels of access have been set, and you have neither of the passwords, then you will not be able to gain
access to EWS information, as in the image below.
3.4.1 Administrator password
Access control is enabled by setting the “Admin account password”, i.e. specifying a password for the user account at
Admin level. You must then provide the Admin password in order to perform any of the following restricted
operations:
16

Cancel, delete or preview a job in the job queue.

Delete a stored job.

Clear accounting information.

Change printer settings on the Device Setup page.

Update printer firmware.

Change the printer's date and time.

Change security settings.

View protected printer information pages.
HP Designjet Printer Series
17
Security Settings
HP Designjet Printer Series
Security Settings
If there is no administrator account, then the restricted operations can be accessed without a password.
3.4.2 Guest password
Once the administrator user account has been set, the administrator can also set up a guest user account by specifying
a password for the guest.
If the guest user account is set up, a username and password are required for all EWS operations: users identified as
guests have access to restricted operations, whilst users identified as administrators have access to all operations.
If the guest account is not set up, a username and password are not required for unrestricted operations.
18
HP Designjet Printer Series
Security Settings
Notes:
19

Some printers only have 1-level password access to the Embedded Web Server.

The networking tab of the Embedded Web Server enables you to set up another password. If the printer
has a EWS 1-level or multi-level password, then the networking password is the same as the general EWS
password. If the EWS does not have password capabilities, then the networking password is only used for
controlling access to the networking area of the EWS.

For most printers that have EWS password capability, it is also possible to setup the Admin password
through Web JetAdmin. Only one level can be set in this way, however, so the Guest password cannot be
set up from Web JetAdmin.

Passwords have no minimum complexity requirements, so the minimum password length is 1 character.

Eprinters with touch screen front panels only allow the use of the limited set of characters shown below
(capital letters are also supported).

These limitations do not apply to printers without touch screen front panels, as the password can be set
using EWS.

Some printer drivers rely on the EWS for creating the preview. In cases where an administrator password
is set, the administrator password will be required to access job preview.

Security Settings
Exclude personal info from accounting
You can enable or disable the option for the printer to send an e-mail containing accounting information. If you enable
this setting, you also need to fill in the destination of the report by using the “Send accounting files to” setting. Please
note that you also have to configure the e-mail server on the Setup Page.
In some cases, customers prefer not to send personal data from the printers via e-mail, and so the option to Exclude
Personal information from accounting e-mail is now available in the Embedded Web server. If this option is selected,
accounting e-mails will not contain personal information (user name, job name, and account ID will be left blank in the
accounting file sent by e-mail from the printer).
This option is typically used for managed print or pay-per-use contracts in order to ensure that only the data
(counters) relevant for billing are being sent by the printer. Personal information about who printed which file is not
required for billing purposes, and can be excluded from the accounting e-mail. This personal information is typically
used for cost allocation within a company.
20
HP Designjet Printer Series
3.6
Security Settings
Disable connectivity interfaces
Depending on the printer series, there are some ports that can be disabled to prevent unauthorized printing and
possible data theft.
You might want to disable the USB printing port to prevent people from connecting a laptop directly into the printer
and printing via USB.
If you have installed a JetDirect card to add extra security features, you might want to disable the onboard Ethernet.
If you enable or disable a connectivity option, the printer will automatically restart. Keep in mind that disabling a
connectivity option could cut off network access to the printer. As a security measure, you cannot disable the
connection that you use to access the Embedded Web server.
Note: If the printer’s front panel becomes locked and you are unable to unlock it, then you should contact HP support
as soon as possible.
21
HP Designjet Printer Series
3.7
Security Settings
Disable protocols
In some cases you might want to disable all protocols that you do not plan to use to access your printer. For example,
you might prevent users from sending files via ftp or connecting through telnet to manage the printer network
settings. You can disable unused protocols through the Mgmt. Protocols option in the Embedded Web Server, or
Network Enable Features in Web JetAdmin.
3.8
IPSec
A Firewall or IP Security (IPsec) policy enables you to control traffic to or from the device by using network-layer
protocols. Either a firewall or IPsec / firewall pages will appear, depending on whether IPsec is supported by the print
server and device. If IPsec is not supported, firewall pages will be displayed and a firewall policy can be configured.
Please note: Before you enable a firewall or IPsec policy, you should make sure that access to your configuration
management settings is secured (for example, through an administrator password). This will ensure that your policy is
not easily disabled through Telnet, control panel menus, or other management tools.
Firewall. Use this page to view or configure a firewall policy. A firewall policy consists of up to 10 rules, where each
rule specifies the IP addresses and services that are allowed by the print server and device. To add a rule, click ‘Add
Rule’. This setting runs a wizard that will help you to configure each rule.

IPsec / Firewall. Use this page to view or configure an IPsec / firewall policy. An IPsec / firewall policy consists of up to
10 rules. As with a firewall policy, each rule specifies the IP addresses and services that are allowed by the print server
and device. With IPsec support, you can apply IPsec authentication and encryption protocols for those addresses and
services. To add a rule, click ‘Add Rule’. This runs a wizard that will help you to configure each rule.
For a detailed description of wizard settings and additional help, visit Jetdirect IPsec/Firewall Help.

CA/JD Certificates
You can request, install, and manage digital certificates on the HP JetDirect print server. Certificates are used to
identify the JetDirect print server both as a valid Web server for network clients, and as a valid client requesting access
on a secure network. By default, the JetDirect print server contains a self-signed, pre-installed certificate.
3.11
Hide IP from front panel
Some printers include an option in the Service Menu, accessible with the help of an HP Support agent only, that
enables you to hide all IP information from the printer’s front panel.
3.12
Encrypt web communications
You can securely manage your network-connected printers using a Web browser and the HTTPS protocol. To
authenticate the HP JetDirect Web Server when HTTPS is used, you may configure a certificate, or you may use the
pre-installed, self-signed X.509 Certificate. The encryption strength specifies what ciphers the web server will use for
secure communications. Supported cipher suites are DES, RC4, and 3DES.
When you enable encryption, the web server encrypts all web communication, forcing all connections to use HTTPS.
You can also configure encryption options to allow both HTTP (unencrypted) and HTTPS connections. In secure
environments, you should choose to encrypt all web communications. Otherwise, sensitive management data
(Administrator Password, SNMP Community Names, and secret keys) may be compromised.
OpenSSL HeartBleed Vulnerability
On April 8, 2014 HP Networking support was notified of the vulnerability known as Heartbleed in the open-source and
widely-used OpenSSL toolkit. The vulnerability allows unauthenticated access to portions of computer system
memory.
HP Designjet products are not vulnerable due to either using a version of OpenSSL that is not vulnerable or are not
using protocol objects affected.

Disable USB drive
You can use this option to disable the use of USB drives, preventing somebody from connecting a device to print or to
scan images.
3.14
Disable firmware update through USB
This option is used to disable the possibility of upgrading the printer by installing new firmware from a USB device.
3.15
Disable direct print using ePrint&Share
Some printers have a feature that enables you to connect a computer directly with a USB cable, and then print without
installing any driver. This can be done by launching the ePrint&Share application that is pre-installed on the printer. It
is possible to disable this feature, however, so that you cannot print via the USB unless you have the driver (or
ePrint&Share) installed on the connected computer.

Disable ePrint Center connectivity
This feature disables the ePrint Center functionality so that users are unable to remotely send items to print.
3.17
User sessions
This feature enables you to set a timeout so that open sessions to ePrint&Share from the printer front panel are
automatically closed if they are not used within the set time.
3.18
Disable internet connection
Disable the direct connection of the printer to the internet. This option also prevents the printer from automatically
performing firmware upgrades.
3.19
Printer Access control
For some printers, when setting an Embedded Web Server Admin password, you also restrict access to certain front
panel features. The protected features on the front panel are:

Network connectivity & Internet connectivity

Control firmware upgrades

Reset factory defaults

External hard disk connection

Security
If a user loses the admin password, it is not possible to reset it and the printer will be locked. There is a service menu
option to reset the admin password. Only customer service agents can do this.
3.20
External hard disk (EHD)
Some printers allow the connection of an external hard disk. Any HP Designjet printer with an internal hard disk uses it
for four main purposes:

Storing the printer’s firmware & resources (media profiles, demo plots, diagnostic plots).

Providing virtual memory for job processing.

Storing/queuing jobs

Storing the printer’s accounting data.
The HP Designjet External Hard Disk was designed for a specific purpose, however. It enables security conscious
customers to preserve the confidentiality of the jobs being printed on their HP Designjet printers.

3.20.1 How the system works
1.
2.
3.
4.
5.
6.
Connect the External Hard Disk (EHD) to the printer’s USB host port.
The printer will detect the EHD and will ask for permission to install it. When you accept, the printer will move
onto the next step.
All of the information normally stored on the internal HD is copied to the external HD.
Your printer’s internal HD partition is then deleted using a highly secure erasing process (DoD 5220.22-M).
The printer is configured to use the EHD as the repository for ALL future jobs (including the temporary
processing storage area).
When the printer is switched off, as a security measure, the EHD can be removed and kept in a secure location.
Notes:




Once the printer has an EHD installed it can no longer be initialized without it.
If for any reason the installed EHD is no longer available (if you should lose the EHD, or the EHD is broken),
there is a mechanism (through a special bootmode controlled with a specific front panel key combination)
that reconfigures the printer to work without the EHD. However in that particular case, all the information
stored on the EHD is lost.
Once the EHD is installed on a particular printer, it becomes fully tied to it. It is not possible to move the same
EHD to another HP Designjet printer without losing the stored information. When the printer detects an EHD
that has been installed on a different printer, it will display a warning. If you then decide to go ahead and use
the EHD on a different printer, the printer will erase the contents of the EHD (once again, using the highly
secure DoD 5220.22-M process)
The EHD has its own software-based encryption mechanism that prevents anyone from reading the contents
of the EHD, for instance, by plugging it into a PC. The encryption system is not a standard system, and cannot
be considered as an extremely secure encryption mechanism (such as the standard encryption system DES,
RSA, FIPS 140), but it does add a level of security that makes it difficult to read the contents by simply
connecting the disk to a PC.
The EHD is not intended to be used as an USB memory stick, that is, to copy documents from a PC, then plug it into the
printer in order to print them.
3.21
Jetdirect Security Wizard (HP T920-T1500-T2500-T3500)
The HP Jetdirect Security Configuration Wizard enables you to configure security settings for HP Jetdirect print server
management. There are 3 levels of Network Security that can be set:
27
Basic
Configure an Admin password which is shared on other tools such as Telnet and SNMPv1/v2.
Enhanced
Disable unsecure management protocols (FTP, Telnet, RCFG, SNMP v1/v2c).
Enable SNMPv3.
Enable SNMPv1/v2 read only access.
Custom
Manually adjust all the settings.

Job storage and PIN printing
Job storage allows jobs to be stored and then printed when required, it also provides features for setting print jobs as
“private”, with a personal identification number (PIN).
To access job storage features, open the printer Properties, and then select Printing Preferences. Click on the Job
Storage tab where the following job-storage features are available:
Print and Store:

After a job has printed, it is stored in the printer, more copies can then be printed from the front panel.
Print and Delete:

Once printed, the job is automatically removed from the printer.
Retrieve from Front Panel (Personal Job):

Use the personal job printing feature to specify a job cannot be printed until you release it from the printer's
front panel.

To preview it in the Embedded Web Server you will need to enter the PIN.
Retrieve from Front Panel (Private Job):

Use the private printing feature to specify that a job cannot be printed until you release it with a PIN. First,
select "Retrieve from Front Panel (Private Job) and then the "Pin to Print" checkbox will be available. If
checked, a 4-digit personal identification number must be set. The PIN is sent to the device as part of the print
job. After sending the print job to the device, use the PIN to print the job. Once printed, it is automatically
removed from the printer.

To preview it in the Embedded Web Server in the Front Panel you will need to enter the PIN.
Note
Some Multifunction devices include Scan Job storage that has two options: Scan and delete (job is not stored in the
scan job queue) and Scan and store (the job is kept in the scan job queue).

Self Encrypted hard disk
The Self Encrypted hard disk ensures data is automatically encrypted every time data is sent to the printer and is
written to the drive. This is achieved using AES 256-bit and FIPS 140 encryption that ensure that data can’t be read or
extracted from the HDD.
Hard disk is protected also with an ATA password that is unique for each printer and changeable when required using
EWS setup tab. This feature allows customers to update HDD password based on their IT security policy periodically.

5. Other security features available only through JetDirect
Some security features are available only after installing a JetDirect 640n or similar internal print server.
4.1 Access Control list
This feature lets you determine the access control list (ACL), which is used to specify the IP addresses on your network
that are allowed access to the device. The ACL is normally used for security purposes and supports up to 10 entries.
The device blocks communications from all other addresses. If the list is empty, any system is allowed access. By
default, host systems with HTTP connections (such as web browser or IPP connections) are allowed access regardless
of ACL entries. This allows hosts to access the device when proxy servers or Network Address Translators (NATs) are
used. However, unfiltered access by HTTP hosts may be disabled by clearing the Check ACL for HTTP checkbox.
Host systems that have access are specified by their IP host or network address. If the network contains subnets, an
address mask may be used to specify whether the IP address entry is for an individual host system or a group of host
systems. For an individual host system, the mask “255.255.255.255” is assumed and is not required.
CAUTION! You may lose your ability to communicate with the device if your system is not properly specified in the list,
or access through HTTP is disabled. If communication with the device is lost, then it may be necessary to restore the
network settings to their factory-default values.
4.2 802.1X Authentication
802.1X is an IEEE Standard for port-based Network Access Control. It provides an authentication mechanism for
devices that want to connect to a LAN.
For most 802.1X networks, the infrastructure components (such as LAN switches) must use 802.1X protocols to
control a port's access to the network. If these ports do not allow partial or guest access, then the print server may
need to be configured with your 802.1X parameters prior to connection.
To configure initial 802.1X settings before connecting to your network, you can use an isolated LAN, or a direct
computer connection via a cross-over cable.
The supported 802.1X authentication protocols and associated configuration depend on the print server model and
firmware version. For more information on 802.1X features please visit here.

Active Directory (AD)
An advanced, hierarchical directory service that comes with Microsoft Windows
servers (version 2000 or later). It is LDAP-compliant and built on the domain
naming system (DNS) used on the Internet. Workgroups are given domain names,
exactly like Web sites, and any LDAP-compliant client – such as Windows, Mac, or
Unix – can gain access.
Adobe PostScript
Developed by Adobe, this is the standard page description language (PDL) for the
graphics arts industry and commercial printing. Many printing devices support
PostScript with a built-in PostScript interpreter
Color Access Control
Settings to determine which users and/or applications are allowed to print in color
Device Password
This is equivalent to the designjet’s web server password. It helps protect the
printer from unauthorized access through remote applications

Domain Naming System (DNS)
Converts host names and domain names into IP addresses on the internet or on
local networks that use the TCP/IP protocol.
Embedded Web Server (EWS)
The EWS resides on a hardware device (such as an HP Designjet) or in the printer
firmware. The EWS enables you to review, configure, and change settings on an
HP Designjet after inputting an IP address into a Web browser from your computer
File System Access settings
(LJ feature)
File system access settings: The File System Access options enable you to
completely disable many of the access points to the printer’s data storage
system. These access points are for various types of usage for the printer. The
options are:

PJL disk access


A one-to-many transmission of data over an IP network.
Internet Protocol Security (IPsec) is a suite of protocols for securing Internet
Protocol (IP) communications by authenticating and encrypting each IP packet of a
data stream. IPsec also includes protocols for establishing mutual authentication
between agents at the beginning of the session and negotiation of cryptographic
keys to be used during the session.
In our case, IPsec is used to protect data flows between the host and the printer.
Job Held Timeout

Job Retention
(LJ feature)
This feature provides job retention options such as private job and hold job. You
will be able to ensure that they are present during printing to provide privacy for
documents in the printer output bins.
Multicast DNS (mDNS)
Also known as Bonjour or Rendezvous, mDNS uses IP multicast with DNS to
provide the capabilities of a DNS server for service discovery in a small network
that does not have a DNS server.
NTLM
NTLM is a suite of authentication and session security protocols used in various
Microsoft network protocol implementations. There are two types of
authentications named NTLMv1 and NTLMv2, version 2 improves security
authenticaion over version 1.

This feature is part of the Job Retention feature. It limits a held job to the selected
time, and then the printer deletes it. You should select a reasonable timeout value
for this setting to allow enough time for a user to walk to the printer to print a job
or to allow time for jobs to print in a queue.
The PJL password feature helps to protect the printer from unauthorized
configuration changes through Print Job Language (PJL) commands. It does not
affect ordinary print jobs. Once the PJL password is configured, the MFP requires it
before it will process any of these commands
This service allows an administrator to use a custom application to upgrade the
printer’s firmware remotely. Since HP recommends using HP Web Jetadmin to
upgrade MFP firmware, you should disable Remote Firmware Upgrade.
This is a network monitoring and control protocol.
SNMP (Simple Network Management protocol) allows users to manage the printer
by using SNMP management tools, such as HP Web JetAdmin. SNMP is also the
protocol for communicating from the printer to the Windows driver. SNMPv3
provides security through user authentication and data encryption
A logical division of a local area network, which is created to improve performance
and provide security. A subnet limits the number of nodes that compete for
bandwidth.

Security Settings
This feature enables administrators to secure Device Functions by requiring users
to log in with a specific Log In Method for each Function. For example, users may
be required to log in with an Access Code or PIN to make copies, yet be required to
log in with a username and password to send e-mails.
Log In Methods: The following Log In Methods are available with the latest device
firmware upgrade:
Group 1 PIN: Requires users to input a numeric code for access when at the control
panel of the device. The numeric code entered by the walk-up user is compared to
the first of two PINs stored on the device by the Administrator. When the PIN is
entered correctly, the user can proceed.
Authentication Manager
(LJ feature)
Group 2 PIN: Requires users to input a numeric code for access when at the control
panel of the device. The numeric code is compared to the second of two PINs
stored on the device by the Administrator.
