The recommended size to print your LWB is the 16 booklet pages to an A3 paper page. This is how it looks (front and back). To do this download the A3 pdf and print the two pages in the pdf back to back. Make sure your printer is set to the A3 tray.
If your printer doesn't automatically print on both sides print the first page then re-insert the page (taking care to make sure you have it oriented properly) and print the second page. Trim any suplus paper around the edge and fold along the lines.
