HP Designjet Printers - Security Features

HP Designjet Printer Series Security Settings

3.20.1 How the system works

1. Connect the External Hard Disk (EHD) to the printer’s USB host port.

2. 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.

3. All of the information normally stored on the internal HD is copied to the external HD.

4. Your printer’s internal HD partition is then deleted using a highly secure erasing process (DoD 5220.22-M).

5. The printer is configured to use the EHD as the repository for ALL future jobs (including the temporary

processing storage area).

6. 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 only)

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:

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.
