It's not a skeuomorphism. Some people actually print out these word processing documents onto actual paper, so they need to be able to see what the document will look like on paper before they print it.
As an aside, I typically use word processors in "Web Layout" (as MS Word calls it) mode until I get to the point where I'm starting to think about print layout. Only then do I switch to "Print Layout".
