When you go to page setup and pick what you want does it still show the preview incorrectly?
I've had no end of problems printing. I must be the worlds worst person for wasting paper.
Is this on old drawings? Or new drawings you have recently created?
There is a way you can create page setups and import them in at the begining of your drawing by going to plot then where it states 'page setup name ' click to add.
Not sure if this helps,
but have a merry christmas anyway.
