Data processing in the bar code data sequence

● In a bar code data sequence following ESC SI, any codes

other than the ESC code are regarded as bar code data.

Continuous two-byte ESC codes (ESC + ESC) are

regarded as a one-byte ESC bar code.

●

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

SI 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
