The Scanner Update Utility must be manually setup by an IT associate before use, for instructions see the release notes. Once set up, it enables an untrained user to update a Zebra scanner's firmware and or parameter settings.
This tool only allows one scanner to be updated at a time. This tool is intended for use in a controlled environment, like a store manager's office.
