No, PowerPoint won't do it either. Graphics apps like Corel and PhotoShop
can do it. Current versions of these are very expensive, but early versions
are fine for this purpose, and can be found for a few dollars at garage
sales and on eBay.
Two other methods --
1. Do the text the right way round. Copy. Paste Special as a picture. Select
the picture, then use 'Flip horizontal' on the Draw menu on the Drawing
toolbar. Graphic quality is extremely variable, and usually unacceptable.
2. Do the text the right way around. Print out onto overhead transparency.
Turn the transparency over and photocopy onto your transfer medium.
