There's basically no difference in the requirements of a B&W negative for scanning or enlarging, and I can't see why a special developer would be required.(posted 8570 days ago)
Most CCD scanners will easily encompass the density range of a properly exposed and developed negative, colour or B&W.
If a negative prints easily, then it'll scan easily; if it's awkward to print, then it'll be awkward to scan. Besides; no desktop scanner is going to get anywhere near to the resolution that Technical Pan is capable of, so what's the point of using it for the sole purpose of scanning?
A new developer just means time and material wasted in testing. Stick with what you know gives you good negatives, and the scans will be fine.I've found that FP4plus scans very well, as does Tmax100 if the density range is curtailed. The main thing to avoid for scanning is excessive grain, and practically any modern film under 400 ISO will give grain fine enough to be invisible to a scanner.
