I have a Brother DCP 7065DN printer connected by USB which stopped working after upgrading to Ubuntu 18.10.
Tried a variety of ways to fix the issue including Command line reinstall of driver
apt-get purge cups
apt-get install cups
dpkg -i --force-all dcp7065dnlpr-2.1.0-1.i386.deb
dpkg -i --force-all cupswrapperDCP7065DN-2.0.4-2.i386.deb
dpkg -l | grep Brother
Everything looks fine on the output:
ii brscan-skey 0.2.4-1 amd64 Brother Linux scanner S-KEY tool
ii brscan4 0.4.6-1 amd64 Brother Scanner Driver
ii cupswrapperdcp7065dn:i386 2.0.4-2 i386 Brother DCP7065DN CUPS wrapper driver
ii dcp7065dnlpr:i386 2.1.0-1 i386 Brother DCP-7065DN LPR driver
ii printer-driver-brlaser 4-1 amd64 printer driver for (some) Brother laser printers
ii printer-driver-ptouch 1.4.2-3 amd64 printer driver Brother P-touch label printers
When I print a test page it looks like it works, print says receiving but nothing prints. Same from a text editor.
Go to http://localhost:631/printers/Brother_DCP-7065DN - printed test page and same thing - looks to work but nothing prints.
If I manually remove/add the printer from the Ubuntu Device / Printers I get a different error message: stopped "Filter failed".
Also tried the RPM installer package, generic lpr and generic cups drivers from the Brother driver site but didn't work either.
