(Peter! I am sorry for also posting my reply to your
private mail to the News, but I felt it better to provide
this knowledge to the Usenet society also.)

Because you already can print out Japanese texts using `kanjips',
what you desire is the better quality.  I doubt following will
answer to your needs, but anyway, I hope this helps.

1. Japanese Laser Printers.

Japanese printer manufacturers sell their products to the domestic
(Japanese) market with kanji fonts installed. It is rare that
Japanese customers buy printers which does not support Japanese
fonts (like *LaserJet*.)  So, if you were a Japanese computer
user and bought a domestic version of Japanese printer, you
already have kanji fonts with the professional quality.

For example, NTX-J is the Japanese variation of LaserWriterII,
which comes with 40M fixed disk on which the outline kanji fonts
already installed. (Of cause, you can freely magnify them to
whatever size desired, writing PoseScript scrits!)

Recent Japanese DVIwares (jdvi2kps, etc.) tend to use printers'
internal kanji fonts, not using the disk fonts.  This is because
your can save your disk space by not installing the kanji fonts
on the disk, or you do not have to buy kanji fonts. (Do you want
to buy additional kanji fonts when you already have pritty fonts
in your printers?)

The technique often used by these DVIwares is to modify the printers
kanji fonts' metric information on run-time, so that they can work
with jTeX's *.tfm font information.  You may feel this dangerous,
because jTeX and printers' kanji fonts are different, but kanji
fonts usually do not have ligatures nor kernings (e.g. for 10pt
kanjis, you may jus think them as 10pt x 10pt squares),  so it
rarely makes design problems.

I usually use jdv2kps, which converts ASCII's jTeX output into
Kanji PostScrit, and it looks great.  (I believe there are some
more others, but I am not too knowledgeable about the subject...)

2. JIS fonts.

Is it the Ntt-jTeX which was available from `utsun.is.s.u-tokyo.ac.jp'?
If it is so, then they might have eliminated the JIS fonts from the
distribution, thinking that no one uses them any more, and they were
just wasting the disk space.  (jTeX was also available via ctapes.)

I still have at hand the JIS fonts which came with jTeX distribution,
which are not proprietary and can be distributed freely.  Then looks
like this:

  jisfonts
  jisfonts/dots
  jisfonts/dots/jfont16.data
  jisfonts/dots/jfont24.data
  jisfonts/gf
  jisjgreek24.300gf
  jisjgreek36.300gf
  jisjgreek48.300gf
  jisjgreek72.300gf
  jisjhira24.300gf
  ...

Consists of the original 16x16 and 24x24 bitmap data, *.tfm, *.gf and
*.pk fonts for Canon CX type (300dpi) printers.  Because they were
automatically generated from 16x16 / 24x24 bitmap data, the quality is
low,  and you might have to modify the jTeX macros to support these JIS
(not DNP) fonts.

If you need it, I can send it to you.  It is approx. 12M, so mail
archives like uuencode/decode may not be appropriate.  Do your site
allow me to anonymously `put' by FTP this thing?  Or, do you know
any Internet sites that may want to keep this in their /pub directory?
If there are, I will gladly tar archive them and FTP.  (Of cause, I
can mail this to you, when no one else have interested on this.)

3. DNP fonts.

DNP (Dai Nippon Printing) fonts are the proprietary Kanji fonts for
jTeX.  I quote their notices from a book titled `TeX Nyuumon'
(Kyoritsu Shuppan, ISBN 4-320-02488-5).  This book has a good description
on NTT-jTeX system.  On ASCII-jTeX (pTeX?) system, refer to `Nihongo
TeX Technical Book' (ASCII Shuppan-kyoku, ISBN 4-7561-0405-3).

Please note that I have no idea if they still provide these services,
because I did not make any contact with them so far.  I am just
*quoting* from the book.  The book is first published in July 1989
(1.5 years ago.)  Things change so rapidly in the computer society,
so do not hold too much expectation.

  (I believe they can be reached via yas@dit.co.jp, usagi@dit.co.jp,
  but I have never tried.  -- mzw_t)

There are several others, but they do not privide DNP fonts (jTeX only),
or for their customers only.  Consult them with the costs and deliveries.
(I thought it cost seveal 10 thousand yens.)  I think it is better you
would better tell them clearly which jTeX (NTT of ASCII) you are currently
using, when you make contact with them.

There is a Japanese TeX User Group, but I am not a member of them, and
unfortunately I do not know the e-mail address of them.  I hope someone
on the net kindly provide us the further information.
