The following conditions are required for barcode printing:
T
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.
T
A barcode is not printed when part of the barcode extends beyond
the right margin.
T
When barcode data and text data are mixed in a data sequence,
barcodes and text are printed in the same place.
T
The start and stop (*) characters of Code 39 are added to human
readable characters.
T
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).
T
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.
T
The barcode print start position (except for POSTNET) is always
7/72 inch above the baseline.
