Like said above, set your paper orientation to Landscape. Change the "Camera" to Parallel Projection, then click on the appropriate stand view (probably "Front"). Now zoom in so that your pattern fills the screen as much as possible without extending off of the screen. Now when you got into Print Preview you should be able to enter "1" into each of the "Scale" boxes. Now when click "OK" your entire pattern should show up on a single page if it is of a size that will fit within the margins.
