Fitting a ZPL 128 barcode on a 2 inch wide Zebra printer label

With a Zebra printer at 203 dpi and 2 inch wide labels, I am unable to fit the 128 barcode correctly.

With ^BY1 the barcode fits but is too tight for some readers to read.

With ^BY2 the barcode prints better but the end gets cut off.

If someone can help with this, would be greatly appreciated.

Solution

  • Your best bet is to specify automatic encoding mode (parameter m in the reference manual). Code128 has a high density numeric mode that encodes two digits for each codeword and will be selected by the ZPL encoder when it sees a string of digits.

    This is your example with automatic mode and ^BY2:
