<P>Developed by Intermec in 1977, Code 11 is similar to Code 2 of 5
|

Matrix and is primarily used in telecommunications. The symbol can

encode any length string consisting of the digits 0-9 and the dash
|

|
||
<P>UPC-A is used in the United States for retail applications. The
|
||
symbol requires an 11 digit article number. The check digit is
|
||
calculated by Zint. In addition EAN-2 and EAN-5 add-on symbols can be
|
||
added using the + character. For example, to draw a UPC-A symbol with
|
||
the data 72527270270 with an EAN-5 add-on showing the data 12345 use
|
||
the command:</P>
|
||
<P><FONT FACE="Courier, monospace"><FONT SIZE=2>zint --barcode=34 -d
|
||
72527270270+12345</FONT></FONT></P>
|
||
<P>or encode a data string with the + character included:
|
||
</P>
|
||
<P><FONT FACE="Courier, monospace"><FONT SIZE=2>my_symbol->symbology
|
||
= BARCODE_UPCA;<BR>error = ZBarcode_Encode_and_Print(my_symbol,

|
||
<P><A NAME="UPCE"></A><FONT SIZE=4><B>5.1.3.2 UPC Version E</B></FONT></P>
|
||
<P>UPC-E is a zero-compressed version of UPC-A developed for smaller
|
||
packages. The code requires a 6 digit article number (digits 0-9).
|
||
The check digit is calculated by Zint. EAN-2 and EAN-5 add-on symbols
|
||
can be added using the + character as with UPC-A. In addition Zint
|
||
also supports Number System 1 encoding by entering a 7-digit article
|
||
number stating with the digit 1. For example:</P>
|
||
<P><FONT FACE="Courier, monospace"><FONT SIZE=2>zint --barcode=37 -d
|
||
1123456</FONT></FONT></P>
|

|

<P>The EAN system is used in retail across Europe and includes
|
||
standards for EAN-2 and EAN-5 add-on codes, EAN-8 and EAN-13 which
|
||
encode 2, 5, 7 or 12 digit numbers respectively. Zint will decide
|
||
which symbology to use depending on the length of the input data. In
|
||
addition EAN-2 and EAN-5 add-on symbols can be added using the +
|
||
symbol as with UPC symbols. For example</P>
|
||
<P><FONT FACE="Courier, monospace"><FONT SIZE=2>zint --barcode=13 -d
|
||
54321</FONT></FONT></P>
|
||
<P>will encode a stand-alone EAN-5, whereas</P>
|
||
<P><FONT FACE="Courier, monospace"><FONT SIZE=2>zint --barcode=13 -d
|
||
7432365+54321</FONT></FONT></P>
|
||
<P>will encode an EAN-8 symbol with an EAN-5 add-on. As before these
|
||
results can be achieved using the API:</P>
|
||
<P><FONT FACE="Courier, monospace"><FONT SIZE=2>my_symbol->symbology
|
||
= BARCODE_EANX<BR>error = ZBarcode_Encode_and_Print(my_symbol,
|

"54321");<BR>error = ZBarcode_Encode_and_Print(my_symbol,
|
||
"7432365+54321");</FONT></FONT></P>
|
||
<P>All of the EAN symbols include check data which is added by Zint.</P>
|
||
<P><A NAME="ISBN"></A><FONT SIZE=4><B>5.1.4.2 SBN, ISBN and ISBN-13</B></FONT></P>
|
||
<P>EAN-13 symbols (also known as Bookland EAN-13) can also be
|
||
produced from 9-digit SBN, 10-digit ISBN or 13-digit ISBN-13 data.
|
||
The relevant check digit needs to be present in the input data and
|
||
will be verified before the symbol is generated. In addition EAN-2
|
||
and EAN-5 add-on symbols can be added using the + symbol as with UPC
|
||
symbols.</P>

|
||
<P>One of the most widely used one-dimensional barcode symbologies,
|
||
Code 128 was developed in 1981 by Computer Identics. This symbology
|
||
supports full ASCII text and uses a three-mode system to compress the
|
||
data into a smaller symbol. Zint automatically switches between modes
|
||
and adds a modulo-103 check digit. Code 128 is the default barcode
|
||
symbology used by Zint. In addition Zint supports the encoding of
|
||
Latin-1 (non-English) characters in Code 128 symbols [1]. The Latin-1
|
||
character set is shown in <A HREF="appxa.html">Appendix A</A>.</P>
|

<P><A NAME="CODE128B"></A><FONT SIZE=4><B>5.1.11.2 Code 128 Subset B</B></FONT></P>
|

<P>It is sometimes advantageous to stop Code 128 from using subset
|
||
mode C which compresses numerical data. The <FONT FACE="Courier, monospace">BARCODE_CODE128B</FONT>
|
||
option suppresses mode C in favour of mode B.</P>
|

<P><A NAME="EAN128"></A><FONT SIZE=4><B>5.1.11.3 GS1-128</B></FONT></P>
|
||
<P>A variation of Code 128 also known as UCC/EAN-128, this symbology
|
||
is defined by the <A HREF="appxc.html">GS1 General Specification.</A>
|
||
Application Identifiers (AIs) should be entered using [square
|
||
brackets] notation. These will be converted to (round brackets) for
|
||
the human readable text. This will allow (round brackets) to be used
|
||
in the data strings to be encoded. Fixed length data should be
|
||
entered at the appropriate length for correct encoding - this is not
|
||
checked by Zint and incorrect length data will result in a symbol
|
||
which does not read correctly (see <A HREF="appxc.html">Appendix C</A>).
|
||
GS1-128 does not support extended ASCII characters. Check digits for
|
||
GTIN data (AI 01) are not generated and need to be included in input

converted to (rounded brackets) before it is included in the human
