I've also noticed that the Brother drivers for Linux are quite old, I sent a support question about it and they denied there being a problem with some sort of market-speak.

Further, a colleague using a Mac is able to print the very same document at higher quality than I am (not sure what printer she has though). Thus, I am leaning towards a printer driver/printer problem on my system. ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos

I am printing on regular copy/printer > paper. 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!

[CentOS] Brother HL-L2360DW printing quality
I have the above printer but have not been able to resolve issues with the printing quality in CentOS 7. 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. Any suggestion what might be wrong? ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos
