• QLn420™

• QLn HC™

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.

Summary of Firmware Release V68.18.7Z If the key cache is cleared all previously established encryption keys are lost, and it will be necessary to go through the key exchange protocol the first time each new terminal is paired with the printer. Display Flip It is now possible to invert the orientation of the display (180°) to make it easier to read in some installations, e.g. when mounted to a wall or a fork lift. It can also be configured to automatically invert when docked in a cradle.

Summary of Firmware Release V68.18.7Z For Groups 0 and J the wlan.country code is set at the factory as shown above, and no changes are permitted. For Groups E, L, A, and B the wlan.region_code is set to “rest of world”, and the default value for wlan.country_code is “not selected”. In these cases it is necessary to configure the wlan.country_code parameter for proper operation.

Summary of Firmware Release V68.18.6Z V68.18.6Z Release Date: 9 November 2012 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.
PAGE 14
Summary of Firmware Release V68.18.3Z Auto-Recovery A new Auto-Recovery feature has been added that will reinstall the firmware if an issue is detected during start up. If a problem is detected the printer will display “Decompressing Files”, then “Writing Files to Flash” and then “Finishing Install” on the LCD, after which the printer will restart. The firmware version on the printer will remain the same after AutoRecovery.
PAGE 15
Summary of Firmware Release V68.18.3Z Common Mirror Application Directory A new SGD parameter ip.mirror.appl_path has been added which allows a common firmware directory for those cases when multiple applications / settings are used. This new command will define the “common firmware directory” for printers to search as a secondary firmware location. This eliminates redundancy and reduces the total amount of storage space required on the server when multiple mirror directories are used.
PAGE 16
Summary of Firmware Release V68.18.1Z 4 dot rows (~ 0.5mm) closer to top edge of the label. This is likely not visible to most users. However, if this should not be the case the media.feed_skip parameter can be used to compensate. To do so set the value to “9”, and this will add back the extra 4 dot rows removed by the firmware. Since this parameter does not exist in earlier versions of firmware, adding this setting to a configuration file would have no impact for those versions.
PAGE 17
Summary of Firmware Release V68.18.0Z • ZPL: Add ZPL configuration section to 2-key report • ZPL: printer does not use stored tear-off setting after power up • ZPL: ^MF command fails to perform media calibration • ZPL: printer delays 2-3 seconds when format contains a ^JUS • 802.11: Fails to connect to an AP configured for WEP with shared authentication • 802.11: Remote auto-connect occurring before power on mirror File.dir_format SGD Command A new SGD parameter called file.dir_format has been created.
PAGE 18
Summary of Firmware Release V68.18.0Z Issues Corrected • Telnet.wml file does not work • Index.shtml and logo.png files show up in E: drive listing • Bluetooth: Potential loss of data when a connection is closed by the host • LCD can become garbled on power up • LCD: display “Restarting” instead of “Shutting Down” after a firmware update • Mirror: unable to FTP index.shtml file • Mirror: files with more than 16.
PAGE 19
Summary of Firmware Release V68.18.0Z • For printing on continuous media with ZPL, we recommend using the black mark sensor. In CPCL, that is the default behavior so no additional steps are required. That is not the case for ZPL. To use the black mark sensor with ZPL for continuous media, set the sensor to the black mark with the following commands, and then send your normal label with continuous content (note that printer uses the sensor to determine if it is out of media): ^xa^mnm^xz ^xa ^mnn ….
PAGE 20
Summary of Firmware Release V68.18.0Z • Avoiding ZPL calibration at startup: The QLn does not automatically perform ZPL calibration at startup to avoid wasting media. In addition, the SGD command zpl.label_length can be used to avoid executing the ~JC command for similar reasons (though ~JC is supported and can be used if desired). This parameter allows the user to specify the length of the media being used in dot rows, presumably in a startup batch file. This is the same command used on the QL Plus.
PAGE 21
Summary of Firmware Release V68.16.3Z Saving the 2-Key Report to a File This feature is intended to facilitate interactions between the user and Zebra technical support. Often a copy of the 2-key (configuration) report is required to debug a problem. Prior to this feature the 2-key needed to be printed and scanned. With this feature the report can now be saved to a text file on the printer’s flash memory, copied to a local PC using the Zebra Setup Utility (ZSU), and then emailed.
PAGE 22
Summary of Firmware Release V68.16.2ZA • CPCL: Print redirection not working when run from a startup file • Ethernet: DHCP fails on soft reset when docked • 802.11: Application corruption when mirroring • 802.11: WEP-128 requires all four keys to be set, should only need one • 802.11: IP roam packets not sent if WEP-128 is used • 802.11: Roaming thresholds using incorrect values, see note below • 802.11: Updated roaming related default values, see note below • 802.
PAGE 23
Summary of Firmware Release V68.16.2Z V68.16.2Z Release Date: 5 August 2011 Enhancements N/A Issues Corrected • PRINT: Feed key does not perform PRESENT-AT • CPCL: TYPE command does not respond when file does not exist • 802.11: Roaming does not work when using WEP encryption • 802.11: IP roam packets sent out before DHCP request • 802.11: Channels mask does not work for channels 12 – 14 V68.16.
