wic.support 30 Report post Posted September 5, 2020 Be sure You are using latest License.exe version 1. Change USB cable and port. 2. Make sure that you are using USB port at the back of the printer. 3. Make sure that USB connection is enabled on the printer:https://forum.2manuals.com/index.php?/topic/80765-how-to-update-and-activate-chipless-firmware-complete-guide/&do=findComment&comment=87426 4.
