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.
The print preview on the left allows you to see the layout.
