[AccessD] Microsoft Office Document Image Writer

Hi all

I just noticed this in my WinXP printer collection.
It can save your print as a file in a proprietary(?) mdi format which
can be viewed and saved as a tiff file.

Does anyone use this for anything useful?
Could it be a valid alternative for printing to a pdf file?
Is it for Office 2003 only?

Several of our clients wish to "go more electronic" and reduce
archiving of paper.
