How do you save your Tabs to a PDF?
While you may think that you'd find a button to press to make this happen, the way to do it is within your browser itself! When you print your tabs (using the print function in your browser), instead of printing to a page, just select "print to PDF" as your output and there you go! A nice formatted tab for you to save to your computer or share with whomever you'd like!
It seemed better to rely on the function within the browser and the work done to format the tabs as printer friendly than writing more code to make this happen.
I hope this helps!
