All bar code symbologies require translation except for Code 39. Simply changing the font will not allow FontWare to do the appropriate translation to create a valid bar code. For the special case of Code 39, changing the font to the Wasp Bar Code Font 39 will allow you to type the characters that should be in the bar code, provided that an * is placed at the beginning and at the end of the string.  To create bar codes using other symbologies in Microsoft Word or Excel, use the FontWare Add-in for that application.
