Does the job as expected. It is easy to select different parts of the page and print only what's required. I like that fact that it does not require a reload of the page, either when clicking the extension or when closing it down.
I would love an 'auto' function that gets rid of stuff automatically, and the user can tweak further if needed (or undo).
It would be more helpful if the buttons & functions had a small tooltip description about what each sub-component does.
If both these are available already, then they need to be highlighted more obviously. Perhaps a (skippable) mini-tutorial when the extension is installed.

Great! Permits editing of HTML elements before printing allowing me to adjust page breaks. Yay!

It only produces zero-byte empty PDF, nothing else.

Eccezionale. Non posso più farne a meno per salvare pagine sfrondandole di tutti gli elementi inutili e rendendole molto più chiare e semplici da leggere.

Best Addon ever tried. Really Thanks
