Adding Prefix and Suffix
The scanner supports adding custom prefixes and suffixes to the scanned data. This feature is useful for data formatting or integration with specific software.

- Then, scan the barcode representing the desired prefix or suffix characters.
- Finally, scan the 'Save Configuration' barcode to apply the changes.
