Basic WYSIWYG printing in GNU Emacs

Here's an attempt to do some basic WYSIWYG printing in GNU Emacs. Sharing
the results of my initial attempt. Use it as you see fit.

   -

   Run M-x ps-print-buffer-with-faces to send output to printer.
   -

   Run C-u M-x ps-print-buffer-with-faces to send output to file (PS
   format).

Does it support characters like čšžđ for some Eastern European
languages?

The code seem to be full Emacs distribution, do you have isolated
code?

Right now it only supports ASCII.

The relevant files are:

I think you would get much better international support if you combine
the emacs printing with my utf8-to-ps (or pdf or svg) program paps.
See: https://github.com/dov/paps . paps support "Pango Markup" so if
you convert emacs faces to pango markup, you can multi face and color
output.

Thinking about it since emacs is gtk based these days, it has pango
and cairo as implicit dependencies, so if these libraries were exposed
through the emacs lisp api, it would be possible to write a
replacement for paps in emacs. :-)

Regards,

Such good idea.

I would like proper printing in Emacs, I guess that I have to research
the function `ps-mule-begin-job' to see how it converts faces to PS
first, to convert it to pango markup.

Package `htmlize' converts buffer properties to HTML, maybe that is
right package to start converting to pandoc markup.

FWIW, when Emacs is built against an appropriately configured Cairo, the
function x-export-frames can export visible Emacs frames (not just the
buffer contents) to PDF, PS, PNG, or SVG.

Nice function and useful for screenshots. 

Just that it is not related to printing buffer text. It shows only the
frame as image.

I have asked Hrvoje, author of htmlize.el package, maybe he can help
doing this.

There's also htmlfontify.el in core.
