You can't - unless saved out as a PDF editable by Illustrator. Typically, when you release files to say a printer, you'd include, or "package" your fonts in a folder or ZIP archive.
Another option is to convert the text to outlines, making them vector shapes. I'd do this if you are 100% certain there will be no copy changes and there are no spelling errors. This is the most surefire way to get the effect you want from a print provider.
I have had nightmarish results when a printer substituted a font that was "close enough", because they had a font conflict. Like, Univers 45, and they have let's say Univers Bold. Or I get a default Courier from the printer back for a proof, because the fonts didn't activate.
