do these same documents print in much better quality on other printers? From the same Linux box? Are they "text" PDFs, or "image" PDFs? where what I call an "image" PDF is a series of pages that are each an image of a page, not the stream of text that makes up the page. I've encountered such images before and you're stuck with whatever quality they have, often poor. If a more normal PDF that just contains the actual text, is it possible that the Chinese font(s) on your system are low quality? Or if they contain embedded fonts, that those fonts are low quality? I don't know offhand how to find out if any particular document contains embedded fonts, but I imagine there are tools that will report that. Good luck!
