Hmmm, I guess I learn something new every day.
I wouldn't have suspected that ghostscript writer could concatenate pdf's and
save so much during compression.
So I just did a test, scanning some tax forms
in 8-bit grayscale to z[0001 --- 0019].pdf using xsane
and then combining using both gs and
I think ghostscript must be writing one dictionary for the whole document
instead of one dictionary per page.
If I take my 16M PDFTK.pdf and re-write it using ghostscript, ghostscript
produces a 8.5M file:
$ gs -q -dNOPAUSE -dBATCH -sDEVICE=pdfwrite -sOutputFile=NEW.pdf PDFTK.pdf
Generally, 1200 dpi resolution for text would be overkill unless you have a
document with extremely tiny print (1-2 point instead of 10-12 point).
They used to recommend 150 dpi or even 75 dpi for scanning documents
containing just plain text. But I scan at 300 dpi and also print ordinarily at
The perl application gscan2pdf will probably do what you need:

I use a shell script bscan for scanning to pnm then conversion to e.g. pdf.
Since my scanner scans better in 8-bit grayscale then 2-bit BW,
I scan in 8-bit grayscale @ 300dpi then convert to bitonal

Have you tried scanning your document using my bscan bash script?
Thanks very much for this, Jeremy, it looks interesting. Unfortunately I
could not get it to run - it complained about not finding 'gamma4scanimage'.
As I got some promising suggestions from the hylafax list I did not pursue
it,

I downloaded the 2006 Samsung Universal Linux Driver and installed.
the new ppd files all seem to pass cupstestppd syntax check which the
ones included in the previous Samsung driver tarball did not. The new
ppd files work fine with cups, unlike the old.
