A question that came up last week at The Foundation and over the weekend at TypeCon:
When a web page is printed – is the web font printed also?
Great question.
From my tests this weekend – No. Not even if the CSS is media="print".
This means the font rendering is specific to the browser and
Update 24 July 2009:
Safari 4.0.2 prints @font-face linked fonts.
As John Daggot describes below, Firefox 3.5.1 does not because of a bug.

This is a bug. But the notion that a browser will ever, ever “install” a font is way off the mark. A browser must guarantee that fonts activated for one document in no way affect the rendering of any other document. And for security reasons, browsers should never, ever “install” fonts for the same reasons they shouldn’t install untrusted content with system-wide implications.
John, thanks for the clarification and confirmation.
