The postscript printer does not bundle Chinese or Korean fonts. Consequently, in Chinese or Korean locales, if you attempt to print from the Mozilla browser, the characters are printed within a box. The Common UNIX Printer System (CUPS) needs to convert the Mozilla postscript fonts before a file can be printed.
Workaround: Perform the following steps.
Click Launch => Preferences => Printers.
Right-click the PostScript printer icon, then select Properties.
Click the Advanced tab.
Set the Ghostscript pre-filtering to Convert to PS level 1.
