Step 1. Download Part "a"
Step 2. Print Part "a"
Step 3. When Part "a" has finished printing, take the stack of papers (which should be ink side down) and place them back in the paper feed tray without rotating, revolving or flipping them in any way.
Step 4. Download Part "b" of the same document, open in Adobe Reader, and print. The printed type on both sides of the completed pages should all point to the same edge of the paper.
Step 5. Make sure the cover is on top, and fold the whole stack in half.
