The test page prints fine but when I print PDF-documents, most recently using Chinese fonts, it is lacking and the pages very hard to read. The settings in the Mate Cups configuration panel are fine and set to 600 dpi, the settings in the printer menu are all OK yet it prints more like maybe 150 or even 75 dpi.

I should have added that the "toner save mode" is off and I also tried to set it to "thick paper" with no difference. I am printing on regular copy/printer paper.
