Find your Brother DCP-L2530DW printer’s IP (make sure it is static, e. g. by setting it up accordingly in your router). Adjust the IP in the lines below.

Scanning

Install brscan5 and xsane.
As root run: brsaneconfig5 -a name="DCP-L2530DW" model="DCP-L2530DW" ip=192.168.1.123

Printing

Install cups.
As root run: lpadmin -p DCP-L2530DW-IPPeverywhere -E -v "ipp://192.168.1.123/ipp/print" -m everywhere

And you are ready to go, enjoy!

PS: If you change the IP, you might need to edit /etc/opt/brother/scanner/brscan5/brsanenetdevice.cfg and /etc/cups/printers.conf.
