printing chinese in mozilla

[Zou Min <zoum@comp.nus.edu.sg>]

Hi,

I have trouble in printing Chinese webpage in mozilla. All chinese characters
are printed as "empty squares".

I have followed the steps in:
http://linux.nctu.edu.tw/web/moto/tips/debian/mozilla_print.html

But still failed, even after I added 2 lines below in 
"/usr/lib/mozilla/defaults/pref/unix.js":
pref("print.postscript.nativefont.zh-CN",          "gb2312");
pref("print.postscript.nativefont.zh-CN",          "BousungEG-Light-GB-EUC-H");


My debian box is using unstable, with:
mozilla                 1.1

psfontmgr               0.11.1
x-ttcidfont-conf        13


Any hint to fix this?
TIA.
