Code 128 Barcode Web Service

The Code 128 barcode is a contiguous, full ASCII encoder. The available character set includes 103 characters, three possible start characters and one stop character. The three start characters equate to the three possible code subsets that are available. The code subset can also be changed within the code stream using shift characters. This barcode generator supports the entire code character set and includes checksum generation.

Control characters can be escaped using the '%' character -- as in %ESC% or %LF%. If you need to include the '%' sign in the code sequence, use '%%'.
