This does not help. The file sizes are more or less the same (if
anything, they are slightly larger).

Original files:
% ls -al scanned_in_office.pdf scanned_on_mx870.pdf
-rw-r--r-- 1 rajulocal rajulocal  331796 Jan  1 11:54 scanned_in_office.pdf
-rw-r--r-- 1 rajulocal rajulocal 1775460 Jan  1 11:48 scanned_on_mx870.pdf

Conversion:
% ps2pdf scanned_in_office.pdf file1.pdf
% ps2pdf scanned_on_mx870.pdf file2.pdf

New file sizes:
% ls -al file1.pdf file2.pdf
-rw-r--r-- 1 rajulocal rajulocal  338539 Jan  2 22:48 file1.pdf
-rw-r--r-- 1 rajulocal rajulocal 1775470 Jan  2 22:48 file2.pdf
