Seems to work well, but I found you need to remember to reset any specific page stettings back to normal after printing a page, or the next web page you print will also print with the last altered settings - even if you use normal print command (Cntl P). Otherwise it works as expected/hoped for.

I used to have the old 'Print/Print Preview' add-on and this one is almost identical and just as good.

Just one thing : I could not find how to add a button to the toolbar. Is there a way to do that ?

If user can choose the language and it will be better.

Just added it - seems to work so far. Yippee!
