  The usblp kernel module must be disabled before CUPS can detect the
  printer.

  Start CUPS after installation and type the command:
      lpadmin -p $MODEL -E -v \$URL -P /usr/share/cups/model/$MODEL.ppd
  where \$URL can be found using the command:
      lpinfo -v | grep -i 'Brother'
  You can also register the new printer using web interface at:
      http://localhost:631/

  You may have to add "$MODEL" to /usr/share/Brother/inf/brPrintList for
  proper operation and extended printing options.
