Code 39 (continued)
In the “Full ASCII Charts” in Appendix C, /D represents $ and /E represents
%. If you configure the computer for Code 39 full ASCII, the computer decodes
the data as $%a because there are three valid full ASCII character pairs to
represent the data.
Other printers encode the data $%a as:
*$%+A*
*$%+A*
The $ and % are valid Code 39 characters in the non-full ASCII character set.
However, the computer will not decode this label if it is configured for full
ASCII because the data is not represented by valid full ASCII character pairs.
To decode the label correctly, you need to configure the computer for mixed-
full ASCII.
When you configure the computer for Code 39 mixed-full ASCII, the computer
will decode both of the labels above as $%a.
Mixed-full ASCII interprets any valid full ASCII character pairs that appear in
the label, but does not require that all data be encoded with a valid full ASCII
character pair. If you are uncertain how your labels are encoded, configure the
computer for mixed-full ASCII, which decodes all valid Code 39 labels.
If you configure the computer for Code 39 full ASCII, you should check for
Code 39 mixed-full ASCII. Mixed-full ASCII does not apply when you
configure the computer for non-full ASCII.
Note: The interpretive text shown under bar code labels does not always accurately
reflect the data that is encoded in the label. The interpretive text represents how the
label should be decoded.
Use this table to help configure your computer.
