Depending on its complexity, you may not be able to print the entire tree. You can print your ancestors, your descendants, or an "hourglass" chart. Even in hourglass mode, you won't get everyone, however. For example, you'll get your parents and kids, but you won't get your siblings or your siblings-in-law. FYI, the focus of the chart is whichever person you have selected at the time to click on the Chart button.
