PowerShow supports a feature called Ticker Show that allows you to show multiple slide shows on the same monitor. We will use this feature to show 2 slides side-by-side on the same monitor. Assume that we have a left presentation that represents the left side of the booklet and right presentation that represents the right side of the booklet. Since we want to show 2 slides from the same presentation side-by-side to form a booklet, we would create a duplicate presentation and make it trail the original presentation by a slide. The steps are as follows:

1. Assume that we have a presentation named Right.ppt. We create a duplicate of this presentation and call it Left.ppt:

   1. Open Right.ppt in Microsoft Office PowerPoint.

   2. Save the presentation as Left.ppt.

   3. Open Left.ppt as well as Right.ppt in Microsoft Office PowerPoint.
       

2. In Left.ppt, insert a new blank slide at the beginning of the presentation.
    

3. Setup Right.ppt to follow Left.ppt as follows:

   1. Select Slide Show | Prepare Sync Show item.
   2. Select Left.ppt as the Master presentation and place a check against Right.ppt as the Follower presentation:
      
      
       
   3. Click OK button.
       
4. Download and store the BookletLayout.ppt in the same folder as Left.ppt and Right.ppt. This layout configures Ticker Show to start the Left.ppt and Right.ppt side-by-side. Open BookletLayout.ppt in Microsoft Office PowerPoint.
    
5. Start Ticker Show to show the Left.ppt and Right.ppt side-by-side:
   1. Select Slide Show | Ticker Show item.
   2. Select BookletLayout.ppt as TickerShow Layout Presentation.
      
      
       
   3. Click the Start Show button.
