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.

See my reply to Fred. Just checked the printer drivers for Linux on the Brother website (https://support.brother.com/g/b/downloadlist.aspx?c=us&lang=en&prod=hll2360dw_us&os=127) and it looks the drivers for Linux are from 2014 and 2015...

The printer driver for Mac OS 10.14 is more recent from 2018 (https://support.brother.com/g/b/downloadlist.aspx?c=us&lang=en&prod=hll2360dw_us&os=10052) and that page also lists a firmware update tool with firmware from July of this year. The update history for the firmware refers only to "improvements" and "software bugs", not very helpful.

Clearly I need to see if I can update the firmware. The most current firmware on the page above is 1.29 whereas my printer has 1.25. Annoyingly the firmware update instructions on this page refers to how to do the update on a Mac...
