This firmware is for use with the following printer models:
• QLn220
• QLn320
• QLn420
This firmware includes all features of the previous V68.19.4Z release.
Changes
• The Link-OS version number is now 2.0.
• Added full support for Profile Manager features. Upgrade to this firmware version to use
printers with the Profile Manager app. This firmware is embedded in the Profile Managers
Resources system to facilitate updating.
• Added support for DHCP option 43. The feature allows the printer to obtain the settings
used to control Cloud Connect weblink connections or Mirror events as part of receiving a
DHCP assigned IP address. This requires that DHCP Option 60 is not empty and that
ip.dhcp.auto_provision_enable
is set to "on".
The package of Cloud Connect/weblink information sent from the DHCP server in the
Option 43 response can include the:
• Server address
• Authentication server name
• User name and password for proxy logins
The package of Mirror information sent from the DHCP server in the Option 43 packet
can include the:
• Server address
Note • When updating from firmware V68.16.3Z or any earlier version, users must first
update the printer to V68.18.6Z, before updating to any later versions. We also recommend
that users power cycle the printer after the update to V68.18.6Z, before moving to any later
versions.
In addition, when updating from firmware V68.18.1Z or any earlier version, we
recommend users
default the printer after updating to a later firmware version. To default the
printer, send these ZPL commands to the unit:
^XA^JUF^XZ
^XA^JUS^XZ
Wait 5 seconds after sending these command and then power cycle the printer.
