Table 8-1 UPC-E Zero Reduction Format
8.1.3 Universal Product Code (UPC-E, send 6 digits), TCI 14
The UPC-E symbology is used in the retail industry and is capable of encoding numerical
numbers 0 through 9 and consists of six digits followed by a check digit that the printer
calculates. This symbology is the same as the UPC-E (TCI 13) with the only exception
being that only the actual 7 numeric digits are used to produce the bar code. The digits
must be valid data for the proper bar code to print. Failure to use valid data may result in an
incorrect bar code. The UPC symbology defaults to an X dimension of 40% or 5.2 mils. To
produce a symbology that is within the specification, a minimum multiplier of 2 should be
entered in the appropriate multiplier parameters (CMX or CMY depending on the field
orientation) to produce an 80% or 10.4 mils symbology.
8.1.4 Interleaved 2 of 5 (I2 of 5), TCI 15
The I2of 5 is a variable length, paired, numerical symbology that is typically used in the
industrial and distribution industries. The I2 of 5 is a paired symbology, which means that
the data string being sent must always be an even number amount. If the desired data to
be sent is an odd amount, simply pad the beginning with “0” to achieve an even amount of
digits. This symbology uses 2:1, 3:1, 4:2, 5:2, 7:3, and 8:3 ratios, which may be selected by
the CGN parameter. The I2 of 5 symbology actually encodes characters in the spaces as
well as the bars. Therefore, the character spacing (CS) parameter must be defaulted.
8.1.5 Code 3 of 9 (Code39), TCI 16
Code 39 is a variable length, alphanumeric symbology that is very popular and is
extensively used in the non-retail, military, manufacturing and medical industries. Code 39
is capable of encoding numerical characters 0 through 9, the English Alphabet (uppercase
only), characters -. *$/+% along with the “space” character. The Code 39 is framed with a
start/stop character represented by the asterisk (“*”) character, which is reserved for this
purpose. This symbology uses 2:1, 3:1, 4:2, 5:2, and 8:3 ratios, which may be selected
using the CGN parameter. Although most specifications require a specific inter-character
