OK, that takes care of my confusion, thanks.
But the original question still stands: where do you make use of
Ghostscript in your code which generates the PS file?
I don't.
Or maybe you
don't use Ghostscript for that (which would be good news), and I just
misunderstood you did? IOW, is Ghostscript a prerequisite for using
your WYSIWYG printing code to produce the PS stuff (as opposed to
sending the PS to the printer)?
It's not. It is only required if one wants to visualize (print preview) it within Emacs. Of course, for development and testing, it's irreplaceable unless you want to waste reams of paper. Hence, I count it as a dependency.
