One of the primary goals of PDF is to preserve document fidelity independent of device, platform, or the software being used to view it. But, according to the PDF specification, a lot can still be left to chance; the ViewerPreferences entry in a document controls the way the document is presented on the screen and can affect the way it’s printed. If the ViewerPreferences entry doesn’t exist, PDF viewers present the document based on the current user’s preference settings. Generally end users don’t modify the initial view settings of their PDF software but different PDF software may have different defaults. The software manufacturer may even decide to change the default viewing modes dramatically from one version to the next as Adobe did when they introduced Read Mode and the Heads-Up Display (HUD) in Reader X. Starting with Reader X, Read Mode is on by default when PDFs are opened in a browser… like it or not.
