Hi Angelo,

Is this to be expected. How can I have a PDF with the font I have set
as default in Emacs?
In short, yes that is expected.
You may want to look at the Variables in the customization group
ps-print-face, particularly ps-font-family and ps-font-info-database.
(M-x customize-group RET ps-print-font RET). More options at the end.
Background: PostScript and PDF use a rather low-level interface for text
and fonts. This translates to a lot of work that an application has to
do, if it wants to use PostScript to achieve effects that are expected
from users nowadays. This work has not been done in Emacs yet.
Emacs just uses the shortcuts that PostScript provides, which means:
* The only fonts that can be selected are those already installed by
default on all PostScript printers (see ps-font-info-database).
(Unless you have a printer where additional fonts can be installed
outside of Emacs.)
* No rendering of characters outside of ISO8859-1, because that is what
those fonts have.
* I believe Emacs does the line wrapping itself, but does not actually
know the metrics of the fonts that exist on the printer, so that
assumes a fixed-width font.
Given, that you are using ps2pdf, your "printer" is actually
Ghostscript, I think. It might be possible to specify a TrueType font
file as the font family and make Ghostscript include that font
automatically in the PDF. But I do not know the syntax for that, or if
it is possible at all without adapting the Emacs code.
Another option is using some other external plain text formatting tool
like Enscript (or ask your favorite search engine ;-)).
Thanks Benjamin! It seems this is a consequence of the fact that we are
using PostScript.
With Kate, for example, I can select 'Print' and than 'Microsoft print
to PDF' and this produces a PDF with the font used by Kate. In Emacs,
instead, 'Print buffer' want to send the buffer to the true printer, one
does not have a menu from which to choose the printer...
In any case, thanks for the clarifications.
Ciao,
Angelo.
