MiKTeX and many other TeX implementations include tools for massaging PostScript into booklet and two-up printing — that is, printing two logical pages side by side on one side of one sheet of paper. However, some LaTeX preliminaries are necessary to use those tools. The twoup package provides such preliminaries and gives advice on how to use the PostScript tools.
