The fact that task T10284 has been merged with this one raises a question for me. The other task was the request for a driver for laser printer-printer MFC-9970CDW for which, as far as I can see, there is no driver at Solus. I don't know if I now have to go through the same procedure as sixtyfive (here above) - with the same or a similar result.
