Unfortunately, ghostscript is not available on our shared hosting plans, and we do not have any plans to install it. If you want ghostscript and cpanel, you would need to sign up for at least the cpanel VPS 200, and install ghostscript yourself.
There are simply not enough resources with shared hosting to accommodate Ghostscript. The application uses a very large amount of memory and would use far too many resources to functionally run on a shared account.
