Hi there,
CSS is the way to control this - check which style sheet is being used for those two templates using either "webmaster mode" or "view source" (alternatively add in your own additional styles if need be).
Note also that different browsers often use a different variation of the specified font (this can not always be controlled) - so it is not always possible to get fonts to show identically in all browsers (the pleasures of the internet

).
This issue of different fonts is also sometimes linked to languages e.g. traditional Chinese font a browser uses by default, is different, than the font it uses for simplified Chinese (and this is over-written by the browser itself and it seems and that it is not controllable via CSS in those instances).
Hope comments help... cheers, Asiaplay
PS: alternative is using an image (and alt text for search engines) if you want fonts to show exactly in a certain format (based on server fonts) - there is a php option for dynamic converting to images on the server side e.g. "Cerdmann" module (search forums and you will get details on this).
