Each subfield’s format is expressed as the format of the Application Identifier the
format of the associated data. Each subfield must adhere to the format specified or else the
printer will be unable to locate following subfields, causing errors generating the bar code.
Any variable length subfield, unless it is the last subfield in the field, must be terminated by
the two characters “#6” (pound+6). These characters are translated as the Code 128
“FNC1” character, which is specified by the UCC/EAN 128 symbologies variable-length field
terminator. The characters “#6” are only used internally and are not printed.
Several Application Identifiers (00, 01, 22, and 8003) specify fields that will have a check
digit as part of their data. A character must be included in the check digit place (although it
need not be the correct check digit). This character is used as a placeholder and will not be
printed. The printer will calculate the correct check digit and replace the character already
there.
8.1.23 UCC/EAN Text Information, TCI 51
The TCI 51 generates the UCC/EAN information as text. This TCI uses the same criteria for
formatting as the TCI 50 bar code. The CGN selects the desired resident font that will be
used to generate this string. The printer will automatically surround each application
identifier with parentheses and add a space character in front of the data when using a TCI
of 51. Do not use the parentheses or spaces when entering the data for an application
identifier field.
8.1.24 Aztec, TCI 52
Aztec is a high density 2 dimensional barcode that can encode up to 3750 characters from
the entire 256 byte ASCii character set. Aztec also has the potential to use less space than
other matrix style barcodes because it does not require quiet zones.
The D193 command is used to receive and process the Aztec barcode with the elements
discussed below.
Once the Aztec barcode data is entered and processed, the barcode image may be placed
using the normal format field by using a TCI of 52.
The sample below shows how to generate a data matrix symbol:
^D193 <---------------------------------Start of Aztec Data
