Hi Beatrice,

which version of PowerPoint do you use? There are two options:

- Use File - Send to Word to create a document which has your slides in the
top half and lines in the bottom half of the page.

- Switch to View - Master - Notes Master and insert lines by just simply
drawing evenly spaced lines in the lower half with the drawing tools. Switch
back to normal view and print Notes pages.

Best regards,
Ute
