Ip of Brother printer ?

Hi.

Having a Brother dcp-j104w wireless printer.

I have tried to change it’s IP address:

Devices on network
  0 SCANNER             "DCP-J140W"         I:192.168.1.14
linux-z96b:~ # brsaneconfig4 -a name=SCANNER model=DCP-j140w ip=192.168.1.12
"SCANNER" is already registered.

How do I change that IP address ?

You have to redo the brsaneconfig but fist to remove the existing config.

brsaneconfig4 -r SCANNER

See brsaneconfig4 in your terminal to be sure about the command

Or maybe manually change the ip in
/usr/local/Brother/sane/bersanedevice4.cfg (mine is brsanedevice3.cfg)
