I am trying to wirelessly print to my Brother MFC 3170, I've installed the drivers from Brother, seem to have done everything correct, but still cannot connect and print to it. The driver shows as installed, location is displayed "network dnssd://Brother%20HL-3170CDW%20series._ipp._tcp.local/?uuid=e3248000-80ce-11db-8000-30055c78d182"

I started the process of formatting my USB drive (64 gb) through GNOME Disk. 2 hours have elapsed and still the process has not completed. Previously I had formatted my 4gb Sony pen drive which formatted in a few minutes. I have also changed the file system to Ext4. Does it usually take this long or should I kill the process?
