Thank you very much Eric S Fraga, H. Dieter Wilhelm, Marcin Borkowski, Nick Dokos and Rasmus for helping me with this! I finally took Nick Dokos's approach, and solved the problem! Here's what I did that worked:
1. In my .emacs, I added: #+BEGIN_SRC emacs-lisp (add-to-list 'org-latex-classes '("letter" "\\documentclass[12pt]{letter} \\usepackage{fullpage} \\usepackage{setspace}")) #+END_SRC 2. In org-mode buffer, I had the following: \\ * Letter to Flora on 2016-03-05 :PROPERTIES: :EXPORT_LATEX_CLASS: letter :EXPORT_LATEX_HEADER: \signature{York} :EXPORT_DATE: 2016-03-05 Saturday :EXPORT_OPTIONS: title:nil toc:nil :END: \begin{letter}{} \opening{Hi Flora,\\} Blah blah blah! \closing{Regards,} \end{letter} 3. C-c C-e l o exporting to PDF 4. Print out the PDF file Thanks again,\\ York On Sun, Mar 6, 2016 at 2:04 PM, Rasmus <ras...@gmx.us> wrote: > York Zhao <gtdplatf...@gmail.com> writes: > >> Hi list, >> >> I've been wondering for a while that when using org-mode to write letters, >> how >> do you export casual a letter that doesn't have from address and to address? > > If you really, really want to use ox-koma-letter couldn't you just set the > addresses to @@latex:\mbox{}@@ or something similar? > > I think a better solution is just to use ox-latex. > > Rasmus > > -- > Dobbelt-A > >
