This character cannot be encoded in Code 39. The symbol will be wrong or will not print.
Restrict the data to the Code 39 character set, or switch symbology. The * start/stop characters are generated automatically — do not include them.
^XA^BY3^FO50,50^B3N,N,100,Y,N^FDitem#42^FS^XZ
Code 39 data containing characters outside its 43-character set (0–9, A–Z, - . $ / + % and space), or containing a literal *.
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.
The bar width is outside the GS1-128 range (0.495 mm to 0.940 mm, 0.495 mm target). At 203 dpi that means ^BY 4 or greater.
Raise ^BY to at least 4 at 203 dpi, or 6 at 300 dpi.
At 203 dpi ^BY2 — the power-up default — and ^BY3 both fail GS1.
