Put your cursor in the very first paragraph. In Format ? Paragraph go
to the second tab and select New Page or Page Break Before (or
whatever it's called).
Select the entire document (Ctrl-A), Copy it (Ctrl-C), put the cursor
at the end of the document (Right-Arrow), type Enter (so there's an
empty paragraph at the end), and Paste (Ctrl-P) the text as many times
as you need.
