Thank you both agsteele and gazumped, I get the paperless notion, but sometimes we might need to print something. I will try the browser, as I can see that the v10 interface has no option.
I did note that you can change margins on a PDF export. However, there is no preview function and therefore you are guessing and at the whim of the export— after three exports I still didn't get the format I was aiming for.
Cheers.
