Please add drivers for Brother MFC-J6910DW. It needs duplex printing capability. Old Brother drivers work, but none have duplex capability.
I would purchase this app if it had a Brother driver that would support duplex printing on my MFC-J6910DW. Unfortunately all Brother printer drivers on this program are ancient. Was told one that no Linux drivers exist for this printer and this was the problem for development. Now Brother has new Linux drivers on their website, so there should be no more problem to implement.
