All it does is take a screenshot and then prints it as an image. I can do that without extensions...

not good at all

Nice idea. Doesn't work.
You click the button, then you can select an area - over multiple pages is awkward to scroll.

Even if you select an area within the visible page, it doesn't work properly and what appears in Print Preview is clearly not the selected area alone.

At least needs ability to select more easily, or select frame.

As of today, 20 March 2019, and for a long time before now, Capture & Print isn't working. Instead of printing the selected area of the page or document, it will print only the entire webpage. Complaint about this problem has been submitted before, but nothing seems to have been done about it because Capture & Print still isn't working correctly.
