Hi Alexandre,

Good questions! Some answers inline, below.

For many languages, DejaVu Sans is sufficient. I have it on my machine already as part of a TeX Live installation. If you haven't already got it you can download it through https://dejavu-fonts.github.io

Yes. It's intended to be similar to most "Open" dialogs (in contrast to "Save" dialogs which do allow you to enter/edit a file name).

I'm afraid Postscript output is rather flakey, but it should at least produce something. In the "Set Print Options" dialog that pops up after you select "Print", have you clicked on "Filename..." to set an output file? The default is no file, not a file in /tmp.

My slime and emacs setup must be different to yours since I couldn't get the above code to work. But below is something similar which does work for me. I've put it in my .emacs, replacing the expression (let ((root (or (getenv etc.

(defconst delphin-home 
  (or (getenv "DELPHINHOME") "~/delphin"))
(add-to-list 'load-path (format "%s/lkb_fos/emacs/" delphin-home))
(require 'slime)

(add-hook 'lisp-mode-hook (lambda () (slime-mode t)))
(add-hook 'inferior-lisp-mode-hook (lambda () (inferior-slime-mode t)))
(setq slime-lisp-implementations
        `((lkb ("~/Documents/delphin/lkb_fos/lkb.darwin_x86_64"))
          (sbcl  ("/usr/local/bin/sbcl" "--dynamic-space-size" "6GB")
		 :coding-system utf-8-unix)
	  (mlisp10 ("/Applications/AllegroCL-10/mlisp"))
	  (mlisp9  ("/Applications/AllegroCL-9/mlisp"))
	  (abcl  ("/usr/local/bin/abcl"))
	  (ccl   ("/opt/local/bin/ccl64"))))

With this, I can start the LKB by doing M-- M-x slime then at the "Lisp name:" prompt typing lkb. I hope you can get this working similarly in your setup.
