Hmm.. but when I use "M-x ps-spool-buffer-with-faces" from Emacs, the 
postscript file *has* the syntax colors!

In other words:

$ emacs -Q
$ C-x C-f foo.c

foo.c has the syntax with colors (font-lock ON by default, right?)

After loading foo.c, do

   M-x ps-spool-buffer-with-faces

and *PostScript* buffer is created. Switching to it (menu Buffers and 
clicking on the item '*PostScript*'):

   C-x C-w  foo.ps


foo.ps has the syntax colors as foo.c when visited by Emacs.


Now if from command line I do:

emacs [-Q] -batch foo.c -f ps-spool-buffer-with-faces --eval "(progn 
(switch-to-buffer \"*PostScript*\") (write-file \"foo.ps\"))"

(with or without the option -Q) it produces foo.ps in BW, *not* with 
syntax colors.


Does it mean that one, to have foo.ps with syntax colors, when produced 
from command lone as above, should setup .emacs as you suggested?

As profane, I would expect that *also* the above command line produces 
foo.ps with syntax colors... Why not? After all, that command line 
summarize in a single command all the steps I described above after 
launching "emacs -Q"... or not?
