Consider the following scenario:
- You have Windows Internet Explorer 9 and Adobe Acrobat installed on a computer that is running Windows Vista or Windows Server 2008.
- You have some content that contains legitimate system fonts that have obfuscated names.
- The Rely on system fonts only; do not use document fonts option in Adobe Acrobat is enabled.
- You print the content to an Adobe PDF writer by using Internet Explorer 9.
In this scenario, the fonts in the print output are replaced by the default system fonts.
