I have two computerrs in the same LAN, where computer A is running Ubuntu 15.10 and computer B is running Ubuntu 16.04. There is a Brother MFC-8860DN multi function center device connected to the network, too. Both machines recognize the MFC-8860DN as a printer. However, machine B does not recognize the Brother as a scanner device, while machine A does.
How to set up the Brother device properly on 16.04? What system output might be helpful?
