Hi All,

We use an HP Bar Code Font to print EAN-13 barcodes on labels. I'm curious if
anyone knows how they work. Until now, we have only needed to print EAN-13's
that start with "978". I would like to print all EAN-13's but cannot figure
out how.

For example, to print the EAN-13 barcode "9780596002725", one would print the
following sequence of characters.

(7ia5j6-AACHCF(

These 12 characters represent the last 12 characters of the number, the 9 is
not represented anywhere so I believe the 9 must come from which characters
use numberics or alphas which determine the first character of the barcode.
The barcode above uses numerics in position one, four, and six. This seems to
work for any barcode starting with a 9 but I can't figure out how to print
EAN-13's with a different leading digit.

Is there anyone out there who understand's this voodoo :)?

Thanks,
Pete
