Adobe pdf is no longer an "available printer"

I am using Adobe Acrobat Pro 9 and have been for a long time on a machine running Windows XP-Pro SP-3. During the installation process, an icon for printing as an Adobe pdf appeared in my available printers folder. I suddenly noticed today that the icon has disappeared. Does anyone have a suggestion regarding how to get that choice back since I use it quite frequently. I tried the obvious "add printer" approach and that leads nowhere. Thanks in advance for any help y'all can offer me. Don
