Group 3 faxes have their own transmission format. It's about 200 dpi,
one bit deep. TIFF files can store this format directly, but any fax
program should be able to deal with other common formats. So long as
it's 200 dpi and one-bit B/W, that's what a fax machine can deal with.

If you want to send greyscale, email a PDF.
