Brother MFC-J6920DW for arm

Hi all, I have a Rock pi 4b and have it running great other than I can’t get my printer to work. In AUR I can build the driver for it but at the end it tells me that it’s not compatible with the arm OS. It’s there a way to port this and if so can I get some guidance, that would be awesome. My printer is Brother MFC-J6920DW


Probably you can edit the PKGBUILD before compiling and change the

arch=('i686' 'x86_64')



Thanks for the reply, I check that out and see if it helps. I will update as soon as I have something.
Where would this file live at?
