V68.19.2Z

Release Date: 15 February 2012

This firmware is for use with the following printer models:

• QLn220

• QLn320

• QLn420

This firmware includes all features of the previous V68.19.1Z and V68.18.8Z.

Issues Corrected

• Printer will no longer skip labels when ^LT and ^PQ are used in a format.

Note • The Dual radio option is only available on the n radio configuration. By default, the

Bluetooth radio is disabled on printers that support dual radio. The Bluetooth radio can be

enabled by using the bluetooth.enable command. When both the WLAN and

Bluetooth radios are enabled, the wlan.power_save feature will be turned off.

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.
