Summary :
Code 128 is a high-density barcode system representing alphanumeric and control characters through different sets, introduced in 1981. This system, comprising sets A, B, and C, allows encoding with 106 characters each. Set A includes upper-case alphanumerics and control characters, B manages the complete 7-bit ASCII set, and C focuses on numeric pairs, enabling compressed data representation. SAP applications must understand the conversion variations in character sets, such as the different "space" values in ASCII and EBCDIC. For EAN-128/UCC-128 applications, the FNC1 control character follows the start symbol directly. Notice that printers could modify these standards, requiring checks on specific printer model capabilities, e.g., via SAP notes on JetMobile BarDIMM for HP or Lexmark. Always ensure the correct start character and control sequences are maintained for data integrity during barcode generation and printing.
