/// The ^BC command creates the Code 128 barcode, a high-density, variable length, continuous, alphanumeric symbology.
/// It was designed for complexly encoded product identification.
///
/// # Code 128 Barcode (Subsets A, B, and C)
///
/// Code 128 has three subsets of characters. 
/// There are 106 encoded printing characters in each set, and each character can have up to three different meanings,
/// depending on the character subset being used.
/// Each Code 128 character consists of six elements: three bars and three spaces.
///
/// ^BC supports a fixed print ratio.
///
/// Field data (^FD) is limited to the width (or length, if rotated) of the label.
