HP Designjet Z5400 PostScript ePrinter Series - Control access to the printer

Front-panel security settings

From the front panel, you can press

, then

, then Setup > Security, to control some of the features of the printer.

USB drive: Enable or disable the use of a USB flash drive.
Firmware upgrade from USB: Enable or disable firmware updates from a USB flash drive.
Enable Internet connection: Enable or disable the Internet connection.

note:
If you disable it, you also disable automatic firmware updates.
Printer access control: Enable, disable, or change the administrator password.

If an administrator password has been set, it must be given in order to perform the following operations:

Change the security settings (including the administrator password itself)
Change the configuration of the Internet connection
Change the Automatic Firmware Update configuration
Enable or disable automatic downloading and/or installation of automatic firmware updates
Restore an earlier firmware version
Reset factory defaults

note:
The administrator password can contain only characters that appear on the front panel's on-screen keyboard. If you set a new password with the Embedded Web Server, it will reject characters that do not appear in that limited character set.

Embedded Web Server security settings

From the Embedded Web Server, you can select the Security tab to control access to the printer in various ways:

Specify separate administrator and guest passwords to control access to the Embedded Web Server
Enable or disable Ethernet and USB connections to the printer
Enable or disable various groups of front panel operations
Use the same security settings that are available in the front panel (see above)

note:
An administrator password may be required.

note:
For more information, see the Embedded Web Server's online help.

Disable your HP ePrint Center connection

You can disable the connection to the HP ePrint Center if required for security. At the front panel, press

, then

, then Connectivity > HP ePrint Center > HP ePrint Center settings > HP ePrint Center connectivity and select Disable.

Disable just puts the remote printing function on hold. If you want to resume using it, you just need to re-enable it in the same menu. No more setup steps are required.

If you want to disable remote printing permanently, select Disable permanently, which erases your printer from your HP ePrint Center account. To use remote printing again, you will need to set it up again from scratch (see Set up your Web-connected printerSet up your Web-connected printer).

note:
You can prevent non-administrators from changing these options by setting an administrator password in the Embedded Web Server (Setup > Security).
