Thanks for your help, Helge.
I install CUPS 1.4.6 and then try to print the pdf document directly. In version 1.4.6, there is no place/area for me to set the locale-filter. Does it mean that there is no need to manually set the filter. (Because in 1.1.2, I can set this printer queue to use zh_TW, the other use zh_CN)
For 1.4.6 CUPS, the print job still fails because the process "pdftops" fails during printing. The message is in the error_log of CUPS as follows:

I am not sure that the failure reason is related to "Ghostscript" version or missing Chinese fonts, or others. Anyone know why?

Thanks a lot.
