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!

Ein prima Druckwerkzeug, genau das was man braucht.

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.
