This is GNU-barcode.

The package is meant to solve most needs in barcode creation with a
conventional printer. It can create printouts for the conventional
product tagging standards: UPC-A, UPC-E, EAN-13, EAN-8, ISBN, as well
as a few other formats. Ouput is generated as either Postscript or
Encapsulated Postscript (other back-ends may be added if needed).

The package is released as both a library and a command-line frontend,
so that you can include barcode-generation into your application.  The
program is released in the hope that is proves useful but without any
warranty, according to the GPL Licence (see ./COPYING).

If you're specifically interested in making an ISBN (Bookland EAN)
symbol, you might try to get "bookland.py" by Judah Milgram
(http://www.cgpp.com/bookland/, whose version 0.06 is also included in
the directory "bookland" within this package, for your convenience).
While my main target is flexibility his main target is strict
adherence to the standards. Bookland is free software like the barcode
library and will probabily have its role in the GNU project.
Bookland.py is a self-documenting program, you'll enjoy browsing its
source code.

Please take the "no-warranty" disclaimer seriously: even though I
spent reasonable efforts to make sure the output is useable in
production you should verify it suits your needs as a faulty bar can
cost you a bundle, and you'll be on your own. It's up to you to verify
that the symbol is valid (and, obviously, I'd like to know about any
problem you encounter). [This paragraph copied verbatim from bookland.py]

I would like to thank both Judah Milgram and Michele Comitini
(mcm@glisco.it) for their help with this tool
