Code 128 character set C consists of numeric data only which allows the effective density of the barcode to be doubled over character sets A or B which allow alpha-numeric data.

So, if your barcode characters are the numbers 0-9 and no letters or special characters, using 128C will print a smaller barcode that fits on the small butterfly labels.

Note: I got the Code 128 info above from "The Bar Code Book" by Roger C. Palmer, Helmers Publishing Inc.

>>>>Another tip if you want to use EPL2 programming: If your Zebra printer comes with BarTender barcode printing software, you can design your label in BarTender and then print it to a text file. The text file will consist of the EPL commands that you can then integrate into your own program.
