Setting up an A1 sheet & printing it

#1
Hi

I cannot get my layouts to view correctly in an A1 sheet. Its all fine if I setup an A4 sheet.

The sheet wont display landscape in preview even though I have selected landscape on the pdf setting.

Also is there anyway that I can have a white sheet displayed on the grey background in layout view? at the moment I just have a grey background.
:?

Thanks
