Which Ghostscript version should I use?
Ghostscript version 9.10 is included as an installation merge module in the Paper SDK (since version 3.4), and this is what we recommend that you use.
Paper SDK 3.2 has added support for Ghostscript 9.x.
Older versions of the Paper SDK should use Ghostscript 8.71 (which also may be included in the installation).
