Yes, exactly, this should be easy. And it *is* easy in other
applications, namely GEdit, Firefox, etc. But unfortunately, it is not
easy in Emacs. That's why I've started the discussion.

Do you have a printer? If so, could you please print the contents of
Emacs 'Hello' buffer and tell us if all the characters you see on the
screen appear on the printed page as well?

I mean that if you have all the fonts needed to render your text in
Emacs frame, and you can print that text using GEdit, you must not be
required to install anything else to be able to print from
Emacs. Currently, you must install so-called BDF fonts (in this case,
the quality would be inacceptably bad, but at least some non-Latin
characters would be printed), or you must install a web browser to be
able to use hfyview.el.

I own a HP LaserJet 1018 which doesn't support PostScript directly, as
don't most of the consumer printers sold today. I'm not a PostScript
guru, but I'm pretty sure that my system indeed does some kind of
PostScript emulation, translating PostScript commands via GhostScript
and then telling the printer what to do in the language the latter
understands.

Maybe -- just maybe -- the Emacs printing works nicely on more
expensive printers which support PostScript directly. I can't tell for
sure because I don't have access to such a printer. As for my setup,
the printing functionality provided by Emacs works bad.

To clear things up: the problem is *not* in the printer, and *not* in
the drivers. Installing the printer on my system was a breeze. I've
encountered the only problematic application so far, and the
disappointing part is that it's Emacs.
