Could you please point to the code which uses or requires Ghostscript,
I don't think I see it in the patch you sent. And since you seem to
be using the HarfBuzz rendering, why do we need Ghostscript at all?
Thanks.
Correction is in order - the screenshot/ rendering within Emacs requires Ghostscript. Printing to printer would use OS specific print commands e.g. lpr on *nix.
