My printer driver doesn't allow me to print several pages per sheet. How can I do it with Writer?
All that you need is in the printing dialog box:
- open the printing dialog box by selecting ▸ or with the Ctrl+P shortcut;
- select the Layout tab;
- the count of pages per sheet,
- or Brochure to create a brochure (4 pages in duplex).
- If your printer cannot do double-sided printing, print twice, by selecting first the back and then the front in the Page sides area on the same tab.
