>This will be on a printer located in Japan.

That's good, but will you be able to test it?  You will need to do
lots of testing.

A Japanese PostScript printer will have a resident Japanese font.  You
need to be familiar with composite fonts, CID fonts, and Japanese
encoding methods (including what the text uses now).  But more than
that, you need to know what kind of resident fonts the printer has. If
it is very recent you can probably assume CID font, if it is older it
may be obscure and barely documented font formats.

The program will essentially select a font; select an encoding; and
send the data, just like for Roman fonts. The first two steps are the
killer.

As well as the PostScript Language Reference manual, you will want to
check out the technotes on http://partners.adobe.com/, some of which
have crucial lists and other information.

If you aren't familiar with Japanese encoding methods, I would
recommend also getting the O'Reilly book "CJKV Information
Processing".

>We have many other apps that create postscripts automatically, and it looks like they are using either MS Gothic or Mincho. 

They will be generating a subsetted font for download to the printer.
That is much more work than what I described. The reason for
subsetting is that a full Japanese font can easily be 20 megabytes in
size.

If you were on Windows with Japanese language support, you could of
course use the Windows API to print, streamlining things considerably-
in fact removing all PostScript puzzles.
