Use ^BC mode D, which strips the brackets and inserts the FNC1 characters.

GS1-formatted data (parenthesised AIs) in a ^BC field with mode N or mode A.
Neither ^PW nor ^LL is set. Both fall back to a value stored in the individual printer, not to a value in the spec — so the same ZPL prints differently on two printers of the same model.
Set ^PW and ^LL explicitly in every format.
