When do I set the DownloadFonts option to No?

Setting the DownloadFonts option to No increases speed and decreases the size of the PDF file. A smaller PDF file also transfers faster over the network and opens faster in a browser.

By setting the DownloadFonts option to No, you let the system use one of the 14 Adobe internal fonts (see also What are the 14 base fonts distributed with Acrobat Reader?) when it attempts to match one of Documaker’s base fonts. In essence, you are trading accuracy for speed and performance, although a high level of quality can still be achieved with this option.

To determine which font to use, the system looks at the Setup Data field on the Other tab of the Font Properties window for the name of the Adobe internal font to use. If a match is not made, the system then uses the TypeFace field on the Description tab. If no match is made, the system then maps the font as indicated here:

Proportional fonts to the Adobe Helvetica font (normal, bold, italic, or bold italic)

Non-proportional fonts to the Adobe Courier font (normal, bold, italic, or bold italic)

The system then checks these fields to determine additional attributes, such as the fonts style (italic or upright) and stroke weight (bold or normal).
