As I understand it, Vista Home editions do not come with any fax support and
you still need thrird-party fax software to do that.
A lot of people seem to think
http://www.snappysoftware.com/ is the thing,
but I have never used it.
BTW although this particular newsgroup is called "Mailmerge and Fax" in the
Microsoft Communities web pages, its "real" name is
microsoft.public.word.mailmerge.fields (i.e. little to do with fax) and you
might be better off looking for the
microsoft.public.windows.vista.print_fax_scan group - I don't know what it's
called in "Microsoft Communities" but you can also use groups.google.com to
look for it.
