How to setup Brother DCP-7065DN printer?

The printer drivers for Brother DCP-7065DN are not in this disto. I am new so how do i get them and install them

Hello there! Welcome to Manjaro!

Not in the Manjaro repos but as usual they are in the AUR! Just run this command to install them:

pamac build brother-dcp7065dn 

thank you but how do i accomplish the following:

To make use of the updated driver, edit your printer in the CUPS
webinterface and select the new driver
Running post-transaction hooks…
Arming ConditionNeedsUpdate…

in your browser (firefox / chrome / …) try in the adress bar: localhost:631 (631 is CUPS)
or maybe use Printers (gui command in KDE)
