I have a new printer (a Brother MFC-9970CDW, so a pretty new one at the hour of me writing) and I tried to connect to it through the "Printing" utility. But at the step where I am supposed to select the driver, my own printer is not listed in there. This is not a problem for me, since I can manually download the driver from the manufacturer site. Moreover it is a GPLv2 software.
Nonetheless, is there a way for me to help the community by uploading any proprietary driver to Ubuntu? I have read this Ask Ubuntu question "How to get my software into Ubuntu?" but it doesn't answer my concern, since the driver I am talking about is actually not a product of my own work.
