The "Print tree" link will always print the portion of the tree that is currently displayed on the screen. You can control what is displayed on the screen by the person you select in the tree, and by changing the display options. To change the display options, click "Show Options" at the bottom of the screen. The three options that determine which people are displayed on the screen are: Parents, Children, and Others. When you change these settings, you are deciding how many generations of each to display.
