I installed an existing MFC-L2700DW printer on my Ubuntu. I used deb package at
https://support.brother.com/g/b/downloadlist.aspx?c=eu_ot&lang=en&prod=mfcl2700dw_us_eu_as&os=128 I connected the printer via WPS and see it in router control panel. Installation finished, however I did get this error:
lpinfo: cups-deviced failed to execute. lpadmin -p MFCL2700DW -E -v usb://dev/usb/lp0 -P /usr/share/cups/model/brother-MFCL2700DW-cups-en.ppd lpadmin: Bad device-uri scheme "usb".
But the installation continues. After it completes and I look at printer properties, I see location = ~empty~ device uri = file:///dev/null make and model = Local Raw Printer.
I can send something to the printer with Libre Office, but nothing ever prints.
I have tried over my network and with the USB connection.
