    3.10 CA/JD Certificates  
    You can request, install, and manage dig ital certificates on the HP JetDirect print server. Certificates are used to 
    identify the Jet Direct print server both as a valid Web server for network clients, and as a valid client requesting 
    access on a secu re network. By default, the JetD irect print server contains a self -signed preinstalled certificate.  
     
    3.11  Hide IP from front panel  
    Some printers includes an option in the Service Menu, accessible with the help of an HP Support agent only, 
    that allows you to hide all IP information from the printer ’s front panel.  
    3.12 Encrypt web communications  
    You can securely manage the network device using a Web browser and the HTTPS protocol. To authenticate the 
    HP JetDirect Web Server when HTTPS is used ,  yo u may configure a certificate, o r you may use the pre-installed, 
    self -signed X.509 Certificate. The encryption strength specifies what ciphers the w eb server will use for secure 
    communications. Supported cipher suites are DES, RC4, 3DES.  
     
    By enabling encryption, the w eb server encrypts all  web communication , forcing all connections to use HTTPS. 
    E nabling encryption  can also  be configured to allow both HTTP (unencrypted) and HTTPS connections. In secure 
    environments, you should choose to encrypt all  web communications. Otherwise, sensitive management data 
    (Ad ministrator Password, SNMP Community Names, and secret keys) may be compromised.

    3.13 Disable USB drive  
    You can use this option to disable the USB  drive preventing somebody connecting a  device to print or to scan 
    images.   
     
     
     
     
    3.14 Disable firmware update throug h USB 
    This option is used to disable the possibility of upgrading the printer by  installing the firmware via a USB device . 
    3.15  Disable direct print using ePrint&Share  
    In some printers, when you connect a computer  directly with a USB cable, you can print without installing any 
    driver.  This can be done by  launching  the ePrint&Share application that resides inside the printer. This feature 
    can disable direct printing  so that you cannot print through the  USB unless you have the driver (or ePrint&Share) 
    installed in the  computer.  
    3.16 Disable ePrint connectivity  
    This feature disables the ePrint Center functionality  preventing somebody printing remotely to the printer . 
    3.17  Disable internet connection  
    Disable the direct connection of the printer to the i nternet. This option would also prevent the printer from 
    automatic ally performing firmware upgrades.

    3.18 Printer Access control  
    For some printers, when setting an Embedded Web Server admin password you are also preventing  access to 
    ce rtain front panel features.  The features protected in the front panel are:  
    •   Network connectivity (including also Internet connectivity and Diagnostics&troubleshooting of the 
    network connectivity) 
    •   Control firmware upgrades  
    •   Setup  
    •   Reset factory defaults  
    •   External hard disk connection 
    •   Security  
     
    If a user loses the admin password, it is not possible to reset it so the printer would be locked. There is a service 
    menu option to reset the admin password.  
    3.19 External hard disk (EHD)  
    Some printers allow the connecti on of an external hard disk.  Any HP Designjet printer with an internal hard 
    disk uses is for four main purposes:  
    •   Store the printer’s firmware & resources (media profiles, demo plots, diagnostic plots).  
    •   Virtual memory for job processing.  
    •   Job storage/queue  
    •   Storage for printer’s accounting data.  
    The HP Designjet External Hard Disk was designed to fulfill one specific use for those security conscious 
    customers that want to preserve the confidentiality of the jobs being printed in their HP  Designjet printers.  
     
    How the system works  
     
    1. Connect  the External Hard Disk ( EHD)  into the printer’s USB host port . 
    2.  The printer will detect the EHD  and will ask the customer for permission to install it. When the customer 
    accepts, the printer will perform the following step : 
    3.  A c opy  will be made of all  the  custome r’s information  that is stored in the internal HD  and copied to the 
    external HD . 
    4.  The customer’s internal HD partition will be deleted after  a highly secure erasing process (
    DoD 5220.22 -
    M).  
    5.  The printer  will be configured  to use the EHD as the repository for  ALL customer jobs (including the 
    temporary  processing storage area) . 
    6.  Once the EHD has being installed, all the customer jobs will ALWAYS be stored in the EHD  
    7.  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 (the customer loses the EHD, or the EHD is  
    broken), there is a mechanism (through a special bootmode controlled with an specific front panel  key 
    combina tion) that reconfigures the printer to work without the EHD . However in that particular case, all the 
    information stored in 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 this 
    EHD  to another HP  Designjet printer without losing the stored information. When the printer detects an EHD 
     
    						
    							HP Designjet  Printer Series        Security Settings  
    25    
    that has been installed on a different printer, it will advise the customer about it. If the customer decides 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 tha t prevents anyone  reading  the contents of 
    the EHD, for instance, by  plugging it into a PC. The encryption system is not a  standard one and cannot be 
    considered as an extremely secure encryption mechanism ( such as th e standard encryption system  
    DES, 
    RSA, FIPS 140…), but it does add a level of security that makes it difficult when trying to read  the contents 
    by just 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, plug it into 
    the printer and to print them.

    5. Glossary  
    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   
    (LJ  feature)   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)  C
    onverts host names and domain names into IP addresses on the i nternet 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 allows you to review, configure, and change 
    settings on an HP Designjet after inputtin g 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 allows
     you  to 
    completely disable many of the access points to the printer ’s data storage 
    system. T hese access points are for various types of usage for the printer. The 
    options are:   
    •   PJL disk access 
    •   SNMP disk access  
    •   NFS disk access  
    •   PS disk access 
    HP recommends e nabling PS Disk Access to allow you to print PS  files, and 
    disable the rest  
    File System Password (LJ 
    feature)
     
     
    The File System Password feature helps protect the printer ’s data storage 
    system options from unauthorized access. With the File System password 
    configured, the printer requires the password before it will allow 
    configurations to features that affect the data storage system. Some of these 
    features are the Secure di sk erase mode, the Secure Storage Erase feature, 
    and the File System Access options.  
    Hide IP address from 
    front Panel  
      Option in the Service Utilities menu of the front panel to show/not show the 
    Internet Protocol (IP) address of your printer. In that way
    , only registered users 
    or network administrations will know the correct  address to submit jobs to the 
    printer   
    HP Web Jetadmin  
    Web-based fleet management software tool for remote installation, 
    configuration, problem resolution, proactive management, and reporting. For 
    more information go to;

    IP multicast  A one
    -to -many transmission of data over an IP network.  
    IPSec 
     
    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 includ
    es 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  
    (LJ feature)  
      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 j
    ob or to allow time for jobs to print in  a queue.  
    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 i n 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
    . 
    PJL Password   
    (LJ  feature)  
    The PJL password feature helps protect the printer from unauthorized 
    configurations 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  
    Remote Firmware 
    Upgrade   
    (LJ feature)  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.  
    Simple Network 
    Management Protocol 
    (SNMP)   This is a network monitoring and control protocol
    . 
    SNMPv3  
      SNMP (Simple Network Management protocol) allows users to manage the 
    printer 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  
    Subnet  A 
    logical division of a local area network, which is created to improve 
    performan ce and provide security. A subnet limits the number of nodes that 
    compete for bandwidth . 
    Authentication Manager  
    (LJ feature)  It allows 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 upgrad e: 
    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.  
    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.  
    LDAP: Lightweight Directory Access Protocol, Requires users to input a 
    username and password that are verified by an LDAP server.  
    HP Digital Send Service (if available): Also known as DSS. Requires users to 
    enter credentials that are verified by the HP Digital Send Service sof tware. 
    (HP Digital Send Service software must be available to use this Log In 
    Method. If no DSS server is associated with this device, walk -up users will not 
    be required to authenticate before using the device.)  
    Kerberos: Requires users to enter a username and password to be verified by 
    a Windows Server
