change print settings across entire document

[Rob]

The margins print margins need adjusting but I can only seem to change it
one sheet at a time. How can I make my change affect the whole document?

I also want to print the gridlines too and I see ow to do that in page
setup, just not across the entire workbook.

Select ALL sheets first (r-click sheet tab)
