How it looks
The text is drawn in a plain font, across the middle of the page, at the opacity you set. 0 is invisible and 1 is solid. It is not a diagonal stamp and it is not an image. A long line can run past the edge of a small page. Shorten the words or lower the size.
The words sit on top of the page content. They do not lock the file, and someone can still copy the text underneath.

Questions
Can I use a logo?
No. This page draws the text you type.
Will the watermark print?
Yes, if the viewer prints the page content. It is part of the page, not a viewer overlay.
Can I put it on one page only?
No. Every page gets the same line. Split that page out if it must stay clean.
