The valid data of each barcode type is described below. If invalid data is
included in the barcode data string, the barcode is not printed.
Barcode type
EAN-13
EAN-8
UPC-A
UPC-E
Interleaved 2 of 5
POSTNET
Code 39
Code 128
The following conditions are required for barcode printing:
Barcode printing is always performed unidirectionally. However,
when it is mixed with raster bit image data, neither barcode nor raster
bit image data is printed.
A barcode is not printed when part of the barcode extends beyond
the right margin.
When barcode data and text data are mixed in a data sequence,
barcode and text are printed in the same place.
The start and stop (*) characters of Code 39 are added to human
readable characters.
The initial data of Code 128 (Set A, B, or C) is identified as the first
data of Code 128, and must be hexadecimal (41, 42, and 43,
respectively).
When Code 128 Set C and Interleaved 2 of 5 are selected, barcode
data requires an even-number data string. However, if an
odd-number string is sent, a 0 is automatically added, making it an
even number data string.
The barcode print start position (except for POSTNET) is always
40/360 inch above the baseline.
