To fix Paul Graham’s On Lisp for printing at Lulu.com, I had to fix the embedded fonts:
gs -dSAFER -dNOPLATFONTS -dNOPAUSE -dBATCH -sDEVICE=pdfwrite \
-sPAPERSIZE=letter -dCompatibilityLevel=1.4 -dPDFSETTINGS=/printer \
-dCompatibilityLevel=1.4 -dMaxSubsetPct=100 -dSubsetFonts=true \
-dEmbedAllFonts=true -sOutputFile=onlisp-fonts-embedded.pdf -f onlisp.pdf
The resulting files:
$ ls -l onlisp*
-rw-r--r--@ 1 pradeep pradeep 1253063 Jun 6 17:35 onlisp-fonts-embedded.pdf
-rw-rw-rw-@ 1 pradeep pradeep 1030575 Jun 6 15:38 onlisp.pdf
