Front Panel Password Protection
The latest release of Link-OS™ adds the ability to protect access to the Front Panel. This new feature requires entering a password before modifying a Front Panel item.
This capability is available to all Link-OS printers with a Front Panel, except for the standard QLn220, QLn320, ZQ510 and ZQ520 printers. To use these new front panel password features on your Link-OS printer, update the printer to one of the following Operating System builds (or later):
Printer Model Type
V68.19.13Z or later
V72.19.13Z or later
V74.19.13Z or later
V75.19.13Z or later
Printers that have this capability have a new item in the “Tools” menu – “Password Protect”, which provides the following three option levels of protection:
o All Front Panel Items that can be modified are protected
o Protects a pre-selected set of items on the Front Panel.
o The pre-selected set of protected items are listed in Appendix 1 in the linked Application Note below
o Which items are protected can be changed by modifying Front Panel WML script files
o None of the Front Panel items are protected when this setting is selected.
Password Protection Commands
There are two Set-Get-Do (SGD) commands and one ZPL command that control the Front Panel password system.
o This SGD sets the password protection level.
o Choices are “all”, “selected”, and “none”. (See above)
- The default value for QLn420 and the Healthcare models of QLn220 and QLn320 is “SELECTED”.
- The default value for ZT230, ZT410, ZT420, ZD500 and ZD500R is “NONE”.
o Sets the current password.
o For security purposes, when retrieving this value via a getvar, only “*” is returned.
o This is the ZPL command that sets the password. (See the Zebra Programming Guide)
o ^KP and display.password.current are two ways of setting the same password.
