Does this font contain ligatures at all?  It would seem to me that
ligatures like ffl would defeat the purpose of an OCR font.  I don't know
what version of OCR B you're using, but the one by Norbert Schwarz doesn't
contain ligatures, and neither do my nor Zdeněk Wagner's TeX packages
based on it, except for some things like Πthat have the status of letters
themselves rather than being pure ligatures.
