You have to pay money for those fonts? Wow. Anyway, what I once did was pull
one of the perl modules that does barcodes. There are loads of them. They
have a function that takes a strings and returns a list of ones and zeros
that represent the barcode.

From here I used that list to make HTML output using two images, one 1x1
white pixel and a 1x1 black pixel. Print that and it worked fine. (Well,
with my cuecat anyway :)

With those perl modules they can also (using the GD library) spit out images
in various formats that also show the barcode. If you want to be really
tricky, you can even generate postscript to do it.

Anyway, hope this helps,
