While PowerPoint will export your slides to several graphics formats, it doesn't give you much control over the size of the images or over the range of slides to be exported. PowerPoint Image Exporter gives you complete control over that and more.
If you're exporting images for pre-press, you don't have to mess around with pixels and calculators and all that; just tell PowerPoint Image Exporter the size you want the images to print and the linescreen you'll be using and let it do the math for you.
