LOGMARS Barcode
The LOGMARS barcode is a style used by the U.S. government. Although it
was meant to print with the human-readable characters placed below the
barcode (B), LOGMARS can also be used the with human-readable
characters embedded in the barcode (E) or not selected (N).

Code 128 Barcode
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 upper-case 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.
the printer chooses the styles which result in the most compact Code 128
barcode for the data to be encoded. Thus, the user does not need to be
concerned about choosing the correct barcode styles since this is done
automatically.
The > (greater than) symbol is a Special character prefix. If a character with a
decimal value less than 32 needs to be encoded (i.e., a control character),
then send a > followd by the character that is decimal 64 higher than the
control code character. If control code characters are encoded, then no
numan-readable characters will print below the barcode. To send the >
character itself, send a >0.
