CODE 128 C: Barcode Library will encode the Char Set C which only supports pairs of digits.CODE 128 B: Barcode Library will encode the Char Set B which only supports ASCII values from 32 to 127.CODE 128 A: Barcode Library will encode the Char Set A which only supports ASCII values from 0 to 95.CODE 128 - default (auto):Barcode Library will automatically switch between code sets to encode the ASCII values.Set the Barcode Type property to CODE 128, CODE 128 A, or CODE 128 B, or CODE 128 C.
