You can use Simplified Chinese fonts just as you use Roman fonts in DPS wrap definitions. The following code sample creates the display in the next figure.
defineps PSWDisplayText(char *text)
/pointSize 50 def
/Helvetica pointSize selectfont
(Hello World) stringwidth pop 2 div neg 0 moveto
(Hello World) show
/cpSize 40 def
/Song-Medium cpSize selectfont
(text) stringwidth pop 2 div neg pointSize neg moveto
(text) show
endps
You can call PSWDisplayText(Chinese text) in a C program to display the designated Chinese text. For an example see the following figure.

Simplified Chinese Solaris software provides TrueType support in DPS.
