Today in June 2019, Brother printers appears to have the best support for printing in Linux. I have installed the drivers on four Linux machines for a Brother DCP-L2550DW with virtually no trouble. Their support pages are the best of the lot in comparison to HP or Canon. Be sure to use the Brother Drivers direct from their website.

A note about installing the Brother drivers. USB or hardwired network connections work without a hitch. However, if the Linux machine is using a wireless connection to the local LAN, I have had to delete the the printer from the web page interface that the install sets up and manually add a new printer where the IP address is entered by hand. The router should have that IP address made static.  The original install sets up a USB port by default, so if you want the printer to work over the LAN WiFi, this fix is required.

The 2550 printer that installed I had some issues with, here are some of the notes.

Don't use YAST to install the drivers or setup the printer

Go to the Brother download page for the printer that you have.

https://www.brother-usa.com/brother-support/driver-downloads#q=DCP-L2550DW  (change the DCP-xxxx to your printer id).

Select Linux->rpm, for OpenSUSE

Download the "Driver Install Tool" and the Linux Printer Driver(rpm), follow the instructions.

Unzip the file(s)

sudo bash Install linux-brprinter-installer-2.1.1-1 MFC-J880DW

You may need sudo to run the install. The install number may be newer than 2.1.1-1 and use the Model number "DCP-L2550DW", etc. instead of the MFC-xxxxx above.

If you want to change from hard wired to WiFi or vice-versa just run the install tool a second time and select the appropriate numbered item and enter the IP number for the wired or WiFi link. There are two MAC addresses, one for each and your router will assign different IP's to each.

I had trouble with the WiFi losing the Setup if the power failed. In which case RESET the network and restart the printer, then re-do the Network setup.
