What’s New in Security, Connectivity, and Flexibility with Link-OS 4.0

Continuing the conversation on Link-OS 4.0 updates, let’s review Security, Connectivity, and Flexibility features included with this release, to ensure we provide the best in class experience to our partners and end-users.


First up are the security options that were launched with Link 4.0. With the goal to meet privacy best practices, we added a new capability of our Link-OS printers to support SHA2 certificates. SHA1 certificates will be supported until Zebra releases Link-OS 5.0.


Within Connectivity several changes and improvements were made to WLAN, Bluetooth, Mirror and ZBI. Under wireless network connectivity, WI-FI roaming and protected management Frames (PMF) were improved to provide a more robust data transmission capability.


For Bluetooth connectivity, the printer is capable of avoiding Bluetooth’s interruptions during network reset. In Dual Radio printers, the Bluetooth radio is activated by default or when the WLAN has been turned off.


The Mirror system of the Link-OS printers also was updated in this release with new features supporting IIS7 and FileZilla servers. The first capability returns codes 125 and 150, including Time and Date stamping, which is normally required for the mentioned servers.  Also, optimization was completed to thefirmware updating” feature through these servers to avoid conflicts, and to speed up the data transference.


Two additional updates were applied and implemented to ZBI and RFID. The former, socket connections, were improved to avoid endless connection when running ZBI programs. The latter, RFID printers, now, support Monza 6 tags. Also, "RFID avoid" was removed to be used again during lower-than-configured darkness set up.


For flexibility, Zebra is trying to build the Link-OS printers more friendly, useful and accessible to end-users.  Zebra engineers looked for ways to provide a better UX experience. A Front-Panel Counter will display the number of labels printed. This new feature can be enabled through of one of the new SGD commands.


! U1 setvar "display.batch_counter" "enabled"

To respond and meet partner and customer requirements, Zebra Included 20 new SGD commands in the new firmware. The most important commands included are:  retrieve print head dpi, keeping the Clock and certificates aligned, Data capture and visibility agent control.  For the full list of commands and implementation, please refer to release notes of the firmware on each Web-Link-OS printer-page.


In future blogs, we’ll review all these new features in detail to share the best practices during implementation. Feel free to contact us for more information.
