Initially looking for ways to further improve its electronic forms software, in November 1991 Delrina had attempted to buy two associated firms that produced Optical Character Recognition (OCR) software, with the intention of incorporating OCR functionality into its forms products. The acquisition deal fell through, though by Fall 1992 Delrina had made a deal with Caere Corporation to include its AnyFax OCR software within its products. This functionality was incorporated into WinFax PRO 3.0 in late 1992, and subsequently in FormFlow Despite the agreement with Caere, the subsequent version of WinFax used Xerox's TextBridge OCR engine instead.
