Subset A: Includes all of the standard uppercase alphanumeric keyboard characters plus the control

and special characters. To select Code 128 Subset A, place an ASCII A (DEC 65, HEX 41) before the

data to be encoded.

Subset B: Includes all of the standard uppercase alphanumeric keyboard characters plus the

lowercase alphabetic and special characters. To select Code 128 Subset B, place an ASCII B (DEC

66, HEX 42) before the data to be encoded. If no start character is sent for the Code 128 font, Code

128 Subset B will be selected by default.

Subset C: Includes the set of 100 digit pairs from 00 through 99 inclusive, as well as special

characters. Code 128 Subset C is used for double density encoding of numeric data. To select Code

128 Subset C, place an ASCII C (DEC 67, HEX 43) before the data to be encoded. Subset C can only

encode an even number of numeric characters. When the data to be encoded includes an odd number

of numeric characters, the last character causes the printer to automatically generate a ‘switch to

subset B’ and encode the last character appropriately in subset B.

Special Character Handling: Characters with an ASCII value greater than 95 are considered special

characters. To access these values, a two-character reference table is built into the printer (see below).

For example, to encode FNC2 into a Code 128 Subset A bar code, send the ASCII “&” (DEC 38,

HEX 26) followed by the ASCII “B” (DEC 66, HEX 41).

Control Codes: By sending these control codes, control characters can be encoded into a Code 128

Subset A bar code (e.g., ABC{DE will be encoded as ABC<ESC>DE):
