Data and Options:

  • The data field can contain any extended ASCII data. The default interpretation of data by readers is in accordance with ISO/IEC 8859-1.
  • An appropriate size will be selected to work around the following restrictions:
    • An M1 symbol is only compatible with numeric data.
    • An M2 symbol is only compatible with alphanumeric data.
  • When the parse option is specified, any instances of ^NNN in the data field are replaced with their equivalent ASCII value, useful for specifying unprintable characters.
  • The version option is used to specify the size of the symbol, either version=M1, version=M2, version=M3 or version=M4.
  • The eclevel option is used to specify the error correction level:
    • eclevel=L – Low (default)
    • eclevel=M – Medium; Not compatible with M1 symbols
    • eclevel=Q – Quality; Only compatible with M4 symbols
  • If unspecified the encoder will select the version of the symbol that is the minimum size to represent the given data at the selected error correction level
