Since Postscript itself does not support Unicode fonts, the burden of Unicode support in printing is on the program creating the Postscript document, not on the Postscript renderer.
The existing Postscript fonts I've seen - .pfa/.pfb/.afm/.pfm/.gsf - support only a small range of glyphs and are not Unicode fonts.
Both the uniprint and wprint programs produce good printed output for Unicode plain text. They require a TrueType font; see section "TrueType fonts" above. The Bitstream Cyberbit gives good results.
The "uniprint" program contained in the yudit package can convert a text file to Postscript. For uniprint to find the Cyberbit font, symlink it to
The "wprint" (WorldPrint) program by Eduardo Trapani http://ttt.esperanto.org.uy/programoj/angle/wprint.html postprocesses Postscript output produced by Netscape Communicator or Mozilla from HTML pages or plain text files.
The output is nearly perfect; only in Cyrillic paragraphs the line breaking is incorrect: the lines are only about half as wide as they should be.
For plain text, uniprint has a better overall layout. On the other hand, only wprint gets Thai output correct.
Generally, printing using fixed-size fonts does not give an as professional output as using TrueType fonts.
The txtbdf2ps 0.7 program by Serge Winitzki http://members.linuxstart.com/~winitzki/txtbdf2ps.html converts a plain text file to Postscript, by use of a BDF font. Installation:
Example with a proportional font:
# install -m 777 txtbdf2ps-dev.txt /usr/local/bin/txtbdf2ps
Example with a fixed-width font:
$ txtbdf2ps -BDF=cyberbit.bdf -UTF-8 -nowrap < input.txt > output.ps
$ txtbdf2ps -BDF=unifont.bdf -UTF-8 -nowrap < input.txt > output.ps
Note: txtbdf2ps does not support combining characters and bidi.
Another way to print with TrueType fonts is to convert the TrueType font to a Postscript font using the
ttf2pt1 utility ( http://www.netspace.net.au/~mheath/ttf2pt1/, http://quadrant.netspace.net.au/ttf2pt1/, http://ttf2pt1.sourceforge.net/). Details can be found in Julius Chroboczek's "Printing with TrueType fonts in Unix" writeup, http://www.dcs.ed.ac.uk/home/jec/programs/xfsft/printing.html.

"groff -Tps" produces Postscript output. Its Postscript output driver supports only a very limited number of Unicode characters (only what Postscript supports by itself).
As of version 4.72, Netscape Communicator cannot correctly print HTML pages in UTF-8 encoding. You really have to use wprint.
As of version M16, printing of HTML pages is apparently not implemented.
As of version 1.0b1, the html2ps HTML to Postscript converter does not support UTF-8 encoded HTML pages and has no special treatment of fonts: the generated Postscript uses the standard Postscript fonts.
As of version 4.12, a2ps doesn't support printing UTF-8 encoded text.
As of version 1.6.1, enscript doesn't support printing UTF-8 encoded text. By default, it uses only the standard Postscript fonts, but it can also include a custom Postscript font in the output.
