I like the idea of the barcode fonts, they print ok, but the barcode reader cannot decipher them, Am I doing something wrong?

The Code 128 symbology has particular start and stop characters and a check sum. Look on Wikipedia or Google for Code 128 to find the "rules".

Additional: Try this site to generate a graphic of a valid symbol (supports a large number of symbologies) if you only need a single symbol (or to generate a symbol to verify yours against):

Hi. I used these fonts but barcode are not identified by the barcode reader. As "rjskoko" said must include the start and stop characters. In wikipedia say that start character in code 128 C is the ascii code 210 but how can I type it? Also as I see there isn't barcode for this ascii in the fonts!

They do not work. The stop character (ASCII 206) is not the same as it appears to this web page!!!

I have confirmed that this barcode DOES work. You must use the correct start and stop characters, and remember the checksum character right before the stop. Go to this page for an automatic string generator so you don't have to manually calculate them:
