So far best tool to print Emacs buffers that I have found is the
command `paps' as it supports correctly Unicode, also emoticons. Thus
you may try by installing `paps' tool from your Operating System
distribution.

Das beste Werkzeug zum Drucken von EMACS-Puffern, die ich gefunden
habe, ist der Befehl "paps", weil es richtig Unicode unterstützt, auch
Emoticons. Daher können Sie es versuchen, indem Sie das "PAPS"-Tool
aus Ihrer Betriebssystemverteilung installieren.

Ich verwende folgende Funktionen:

(defun rcd-command-output-from-input (program input &rest args)
  "Return output string from PROGRAM with given INPUT string and optional ARGS."
  (let* ((output (with-temp-buffer
		   (insert input)
		   (apply #'call-process-region nil nil program t '(t nil) nil args)
		   (buffer-string))))
    output))

I am too often using landscape, you can adjust it for your needs.

(defun rcd-paps-process (text &optional format title &rest args)
  (let* ((format (or format "pdf"))
	 (title (or title (buffer-name)))
	 (length (length title))
	 (max 45)
	 (title (if (> length max) (substring title 0 max) title)))
    (apply 'rcd-command-output-from-input "paps" text "--format" format "--landscape" "--title" title "--header" args)))

(defun string-to-file-force (string file)
  "Prints string into file, matters not if file exists. Return FILE as file name."
  (with-temp-file file
    (insert string))
  file)

(defun rcd-paps-text-to-pdf (text &optional file-name title)
  (let* ((output (rcd-paps-process text "pdf" title))
	 (file-name (or file-name (concat (file-name-as-directory (getenv "HOME")) (read-string "File name without .pdf extension: ") ".pdf"))))
    (string-to-file-force output file-name)))

(defun rcd-paps-buffer-to-pdf-view ()
  (interactive)
  (let ((output (rcd-paps-process-buffer))
	(file-name (rcd-temp-file-name nil "pdf")))
    (sleep-for 1)
    (start-process "evince" nil "evince" (string-to-file-force output file-name))))
