I don't know how ghostscript works per se. You're sending it to the printer,
or the screen?
The point is the PS interpreter in the printer has no good way of knowing
you're done with the page, unlike ghostscript, so you have to add specific
code to the postscript on a printer to say "I've generated the bitmap, so
send it to a page now." IIRC, that command is called "showpage".
Ghostscript on the screen renders as it interprets, so that's different.

Ghostscript also refuses to display anything until you perform a
showpage operation. (Or the deprecated copypage operation, for that matter.)

Actually, the right answer is to start with the incomplete list, and make
sure that nothing that used to work breaks when you add more.
But the real point of this post: A sample unit test for you:

Well, that too.
