screenplay format

When I work in screenplay format the spacing and margins are wrong. The line spacing is so tight there’s a slight overlap. The left margin doesn’t print at the 1 1/2 inch standard. The right margin is indented so far as to leave a fairly narrow ribbon of print. I have tried to reset it but no matter what I do to margins or page set ups it comes out the same or worse. I have a friend with Scrivener and have copied her settings and still no better. Help!
