My reading and listening comprehension features use a plugin called Inline Spoilers that hides the English translation when you first visit a page, allowing you to read or listen to the French before you check the English translation. Just click to read the translation of that section of the text. You can click again to hide it.
To print the French text along with the translation, you first need to click to reveal each section. Your printer can only print what is visible on the screen.
