Try setting the "Page Setup" to 1 page wide by 1000 tall.
This will force the output to fit into a single page wide and should help resolve the issue you're facing (see attached screen shot).
You will also need to go in to each page and set the appropriate orientation, margins and page size (A4 vs. 8 1/2 x 11...).
NB: The margins in your template are not the same for all sheets.
Hope this helps
