Unprotect protected PDF files
Authored by: mfripp on May 11, '09 02:34:19AM

The newer versions of Preview (at least OS X 10.5, and maybe earlier) respect the "do not print without a password" setting in PDF files, so the hint above won't work for them. However, it is possible to create a completely unprotected version of any PDF file using ghostscript. A command like this should work:

gs -sOutputFile=MyNewFile.pdf -sDEVICE=pdfwrite -dNOPAUSE -dbatch -q MyProtectedFile.pdf

You may need to type "quit" at the command prompt after gs finishes processing the file.

I can't remember whether ghostscript came with OS X or whether I installed it from somewhere...

This is a great hint, thank you, it saved me a lot of time when no printer was in sight.
