Located directly below the Orientation options is the Scale section. Here you can modify the dimensions of a page for printing purposes. For example, by modifying the value to 50%, the web page in question will be printed at a scale of half the original page.
By default, the entry field for this value is grayed out and not editable. This is because the Shrink To Fit Page Width option is checked. When activated, the browser will be instructed to print the web page in a fashion where it is modified to fit the width of your printing paper. If you are interested in altering the scale value manually, simply remove the check mark from this option and replace 100% with the value of your choice.
