Each subfield’s format is expressed as the format of the Application Identifier number + 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.
8.1.24 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.
8.2 Bar Code Rotation
When 0 and 180 degree bar codes are X multiplied (CMX), the space between characters is
also multiplied by the printer internally to maintain the correct ratio. When multiplying bar
codes use the default value for the spacing element (SP) in the field format parameters. On
some bar codes that allow spacing to be adjusted, spacing may be increased from the
default and not reduced to a smaller spacing.
When 0 and 180 degree bar codes are Y multiplied (CMY), the result is the actual height of
the bar code in thermal dots. If the Y multiplier (CMY) is not multiplied, a bar code with a
vertical length of one dot would be produced. For example: If a one inch high bar code is
desired using a 300 dpi print head, 300 should be inserted for the CMY value.
When 90 and 270 degree, ladder or vertical, bar codes are X multiplied (CMX), the result is
the actual width of the bar code in thermal dots. If the X multiplier (CMX) is not multiplied, a
bar code with a horizontal length of one dot would be produced. For example: If a one inch
wide bar code is desired using a 300 dpi print head, 300 should be inserted for the CMX
value.
When 90 ° and 270 ° degree bar codes are Y multiplied (CMY), the space between
characters is also multiplied by the printer internally to maintain the correct ratio. When
multiplying bar codes use the default value for the spacing element (SP) in the field format
parameters. On some bar codes that allow spacing to be adjusted, spacing may be
increased from the default and not reduced to a smaller spacing.
