Subject: ps-print-buffer only knows about some fonts for MacOS Preview

I use ps-print to produce a PostScript file that I open in MacOS Preview to
double-check before printing.  I'd like to be able to use Hack as a font
rather than Courier.  Right now, Hack isn't recognized along with other
installed fonts, but I can't tell why some work and some don't.


Following the directions in ps-print.el, I tried to add Hack as
a Courier replacement.  I removed the comment and updated this line:

3 cm 20 cm moveto  10/Hack-Regular ReportFontInfo  showpage

Opening the resulting PostScript file in Preview.app gives this error:


PostScript Conversion Warning

Converting the PostScript file "temp.ps" produced the following
warnings: "Hack-Regular" not found, using Courier.


Similarly for "Hack" or "Hack-Italic."  In trying to debug the problem,
I checked fonts on my laptop at random to see if any worked.
AmericanTypewriter-Light works fine while AmericanTypewriter gives the
same error, even though both are in the same directory and seem to be
otherwise similar.  I'll paste the details of those two fonts below, but
I think there must be something in the PostScript generated by ps-print
that doesn't load all the fonts.  Pages, for example, generates
a PostScript file with Hack, but it looks remarkably different than what
ps-print generates--so I'm not entirely sure what to compare.

I'm not sure what to do next to debug this: my PostScript knowledge is
minimal.  Does anyone have a sense of how to figure this out?


Emacs 26.3

Is this really an error in what Emacs emits? My PostScript is incredibly rusty, but with the PS font name reported by Font Book, it seems to work for me. I wrote a .ps file by hand:

------------- start of file -------
%!
/AmericanTypewriter findfont 12 scalefont setfont
100 400 moveto
(Hello! I'm AmericanTypewriter!) show
showpage
-------------- end of file --------

and it was accepted by Preview in macOS Mojave. American-typewriter-Light worked just as well, and in both cases the correct font was used. I don't have your Hack font installed, however.

Thank you, and best of luck. Do tell us if anything Emacs-specific turns up.

Thank you!

This appears to be a setup-dependent MacOS bug, which I've sent that
way the best I know how: https://discussions.apple.com/thread/251495268  and  Feedback FB7744710
