Some scanner
software can output PDF directly. That's
probably the easiest approach.
The Lexmark W810 and C710 I used to use did that, but it
was not G4 compressed (not a big deal, but something to
be aware of).
If you have the full Acrobat package (not just the
free
Acrobat Reader), it can import common image formats such as
TIFF and JPEG, but you have to do it one at a time. There
Acrobat 4 can import up to 50 files at once. So if you have
scanned to 50 individual TIFFs you can import them all in
one go (it's not that speedy though!). I expect that
Acrobat 5 can also import, but I could never find the
right menu ! What it can do (which 4 and earlier could not)
is spit out a PDF file as individual G4 compressed TIFFs.

If you don't have acrobat, but have a current RedHat Linux setup:
If you start out with tiff images, you can use the following sequence
to end up with a pdf (as long as you don't get any fatal errors), assuming
that the original tiff files are named something like 't1-001.tif' ...
't1-999.tif'
and the final file will be named 't1.pdf'
tiffcp t1-*.tif t1.tif
tiff2ps -a t1.tif > t1.ps
ps2pdf t1.ps t1.pdf
rm t1.tif
rm t1.ps
tiffcp is used to merge all the tif files into a single tif file.
tiff2ps converts the tif file into a postscript one (very big file)
ps2pdf converts the postscript file into a pdf one (smaller than
the postscript)
and rm killes the intermediate files.
There are some 'tif' formats that the programs will not handle,
but it will give you a nasty error message if you try one of those.
