Try taking a screen shot and printing it out.
Press 'Print Screen' at an appropriate point during the slide show. (Absolutely nothing will seem to happen at that point !). Open Microsoft Word, with a blank document in landscape format. Right-click in the document and select paste. You'll then have a picture of your screen, which you can resize by dragging the handles at its corners or edges. Print that out (onto photo paper, using the photo-quality printing options that you can access from the Print dialogue box) and crop off the bits you don't want.
