How to use the symbology ID for ISBN and ISSN
ISBN and ISSN bar codes are normally 10 digits in length (see the PCL 5 section above for a
complete description), but they have extensions known as ISSN+2, ISSN+5, and ISBN+5. Obtaining
these variants is not done by adding a “-5” or “-2” to the end of the Symbology ID, but by adding two
or five more characters to the string that defines the bar code. For example, an ISSN+5 bar code
can be defined in PostScript as follows:
%!PS
