ScanSoft OmniForm Developer Edition 5.1 is the easiest, quickest way to migrate your forms to InfoPath. Simply drop your paper form on the scanner, or "print" static digital forms like PDF and Word forms, to OmniForm and within seconds you have a form on screen that looks identical to the original file or paper form. At this point you can choose Save As InfoPath from the Save as menu, and publish the form out to the InfoPath (.xsn) format.
