The extension works by removing objects from the page, using the buttons Sans Images or Avec Images, and then using the button Imprimer to print the page.
It can remember the last action and undo that action only. If you want to undo several steps, reload the tab in the browser. Also, please note that if you remove images, you cannot use the button Avec Images to reinsert them, you have to use the Retour undo button to get them back and then use the "Avec images" button to prepare the article for printing with images.
However, since the removal operations are cascaded it does work to first use Avec Images and then if images are not wanted to use Sans Images to remove the images also.
To change the print font size, use the slider and then confirm the new setting by clicking Sans Images or Avec Images. Going back and forth between font sizes will confuse FF and after a few turns it is best practice to reload the page and start fresh.
