This means a higher level of cybersecurity, including requiring you to set an admin password on first start. Several insecure services are turned off by default and Wi-Fi uses more modern encryption. Some printers also have a PIN lock on the control panel. New Zebra models such as the ZT series, ZD series and ZQ series are included. Older devices can become "EU RED ready" by updating the firmware to Link OS 7.4.2 or later.
