Sometimes I want only some paragraphs of text to be printed, and not the whole document. If the documents are large, I almost need a whole tree just to have those 2 paragraphs on paper.
If I want some text of a memo next to me (f.e. if I'm solving a problem described in it) I get the header, footer, reply history and other blabla in it too. I always end up with more than a single sheet.
An extra option "Print selection" would do the trick.
