In PowerPoint, your slide backgrounds go all the way to the edge. But when you print, there’s still a white margin around the edges. This problem comes from the design of most printers, which have an area at the edges of the page where they can’t print.
PowerPoint can’t change this printer limitation. But there is a workaround that you can try.
- Click Design > Slide Size > Custom Slide Size.
- Under Orientation, click either Portrait or Landscape, depending on the orientation of the slide you want to print.
- Click View > Notes Master.
- In the Placeholders group, uncheck the boxes for the text placeholders (such as Page Number, Header, Footer, and Date) that you don’t want to print.
- Drag the slide image so it’s slightly smaller than the full page. Check what the trailing margin on your printer is, and make the margins on both sides of your notes master at least that large.
- Click File > Print > Print to print a trial page. If it’s off center, click View > Notes Master and try to center the slide image and print again. You might have to repeat this step several times to get the look you want.
More about margins
Most inkjet printers create irregular, nonprintable margins, with the margin at the end that prints last generally wider than the margins on the other three sides.
When PowerPoint prints slides, it sends the slide image to the printer at whatever size the printer and printer driver specify as the largest printable size. But PowerPoint can’t control where on the page the printer places the slide image. Some printer drivers include a "fake" page size that allows even margins but a smaller image that they may automatically center on the printed page. If your printer has this feature, it should allow you to get centered printouts.
