● In a bar code data sequence, any codes other than the ESC

code are regarded as bar code data.

In a bar cord sequence following ESC SI, continuous two-

byte ESC codes (ESC + ESC) are regarded as a one-byte

ESC bar code.

● In a barcode data sequence following ESC SI, ESC+ SO

and ESC + ESC are valid and the other ESC sequence are

ingnored. The ESC code and the following data, two bytes

in all, are discarded.

● When a start or stop character code (e.g., * code of Code

39) is input in a bar code data sequence, the bar code data

sequence stops if bar code data has already been input in

that sequence. The data that was input is valid and

converted into a bar code. If not, the bar code data

sequence does not stop and the code is discarded.

● When 68 bytes of data is input, the bar code data sequence

ends automatically.
When Code 93 or Code 128 is selected, the bar code data

sequence ends when the amount of input data, including the

automatically inserted control character, reaches 68 bytes.
