[cups] Brother vs cups, 0,1 in favor of cups

Fri Nov 2 14:59:51 PDT 2018

I’d suggest to do the following:
(1) execute:
	cupsctl —debug-logging
(2) print e.g. a color image using the lp command from the command line
(3) execute
	grep ‚Job xxxx‘ /var/log/cups/error_log
where xxxx is the job ID the lp command wrote to the terminal window.
(4) post the grep output to the list, so that we can see which filters are used to print
     the file.
(5) post the PPD for the printer (append a „.txt“ to the file name, as the list only accepts text file attachments).
