Previewing Adobe PDF documents without embedded fonts
You may want to see a preview of how substituted fonts will look in your Adobe PDF
document to help you decide which fonts to embed.
To preview an Adobe PDF document without embedded fonts:
In Acrobat, choose Advanced > Use Local Fonts to specify whether Acrobat should
ignore the fonts installed on your system. When Use Local Fonts is not selected, Acrobat
displays the PDF file using substitute fonts for all fonts that are not embedded. If a font
cannot be substituted, the text appears as bullets, and Acrobat displays an error message.
You can also print the PDF file using substituted fonts.
