Re: [Matplotlib-users] mathbb and eps export

The main difference is file size.  When ps.useafm is True, the fonts 
don't have to be embedded because it uses fonts that are required to be 
available with every Postscript interpreter.  When it is False, the 
fonts have to be included as part of the file, resulting in larger file 
sizes.
