^FS: Field Separator (ZPL)
Ends the current field.
Field separator closes the field that was opened by an origin and data command. Without it, the next command can be swallowed as more data. Every field in a format should end with a separator before the next origin or the format end. The separator does not print anything by itself and does not change printer settings. The graphic field helper emits a separator after the hex image so the format can end cleanly.
