Description
While many barcode styles are limited to numbers, Code 128 can encode
numbers, letters, and other symbols commonly found on keyboards, such as
@, # and %. The Code 128 barcode is similar to three barcodes in one. The
three barcode styles are called Code A, Code B, and Code C. Each barcode
style is designed to encode certain types of data in the most compact way.
•
Code A encodes uppercase alpha, numeric and control codes.
•
Code B encodes upper and lower case alpha and numeric codes.
•
Code C encodes digits in pairs.
A single Code 128 barcode may consist of all three Code 128 barcode styles
A, B and C. The printer chooses the styles which result in the most compact
Code 128 barcode for the data to be encoded. Do not be concerned about
choosing the correct barcode styles as this is done automatically.
The ">" (greater than) symbol is a special character prefix. If a character with
decimal value less then 32 needs to be encoded (i.e., a control character),
then send a ">" followed by the character that is decimal 64 higher then the
control code character.
NOTE:
Control characters conflict with DC4, SUB. These characters are
encoded by using the ">" sign following a number that is 64 dec.
higher than the control character.
