Från Word-hjälpen: "Start a new, blank document. On the File menu, click Page Setup, and then click the Margins tab. In the Multiple pages list, select Book fold. If your document is not set to landscape orientation, Microsoft Word sets it to landscape. In the Inside and Outside boxes, type or select the amount of space you want for the inside and outside margins. If you need even more space along the fold to accommodate binding, type or select the amount of space you want in the Gutter box. In the Sheets per booklet list, select the number of pages you want to include in a single booklet. If the number of pages in the document exceeds the number of pages you select for a booklet, Word prints the document as multiple booklets."
