Sorry,
To make a postscript in windows, have your page you have made in FrontPage and go to print. Check off "Print to File", save your .prn file where you wish. Acrobat Distiller is what makes your PDFs, should be in your program list.
Doing any of the auto make PDFs, Print to PDF.. your options are limited if none at all, or very watered down for ease of use. Ease of use is not always the best way to go. When you load Distiller you get the full range and control of settings when making your PDFs. Compression, Colour management, font options, ...ect ect.
You can use one of the pre done settings, maybe Web would be best for you. Or you can go in and create your own custom settings if thats your bag.
Once you've set your settings, Drag and drop your .prn file onto the Distiller window and it will create your PDF.
Cheers
