ZPL - how can we increase width of ^BC (Code 128) bar code

Am doing a formatting of barcode label. We are using Zebra Programming Language , ^BC (Code 128) bar code

As i increase the size of ^FD Field Data , the barcode width is increasing.

But how can i print a broader bar code for a fixed small length data.

I saw magnifying factor for some other types like UPC E barcode.

But i dont find any magnifying factor for ^BC code 128 barcode.

I put some space and it increase width but not effective while reading barcode
