Setting up an A1 layout

#1
Hi.

I have been unable to get this to work and cant see what I'm doing wrong. When I setup an A1 layout and try to print to a pdf creator it just wont centre on the page correctly. The only way I've been able to get it nearly right is by selecting extents rather than layout and then choosing fit to page. This means the scale is fractionally out (1.0=0.08) and yet if I select a 1:1 scale it throws the whole thing off the page. Also when in paper space should the sheet area be displayed in a different colour from the background as it is in autocad? If so, mine isnt.

Can someone please point me in the right direction.... I need to earn some money and I cant without the PDF's !!!! Help
