Comment 224 for bug 1728012

Just a reminder to those of us using Brother DCP or MFP's: I repeatedly
find that the only way to properly install the printer and scanner drivers
is to use the "Installer Script"(i.e. 09/13/2018
(2.2.1-1)) provided on the model downloads page(see below) and to follow
the directions given _explicitly_(to-the-letter, no exceptions)! I've tried
to install a recently updated scanner driver(i.e. 01/21/2019
(0.4.7-1)) by itself as an upgrade to the currently installed one and even
re-ran the setup command(i.e. Brsaneconfig4 -a name=(name your device)
model=(model name) ip=xx.xx.xx.xx) for my network(Wi-Fi) DCP-L2550DW, but
it does not work that way. I can't stress, enough, the apparent need to
re-run the "Installer Script", exactly as shown--below, in order for
everything to work!

How to Install

Step1. Download the tool.(linux-brprinter-installer-*.*.*-*.gz)

The tool will be downloaded into the default "Download" directory.
(The directory location varies depending on your Linux distribution.)
e.g. /home/(LoginName)/Download

Step2. Open a terminal window.

Step3. Go to the directory you downloaded the file to in the last step. By
using the cd command.

e.g. cd Downloads

Step4. Enter this command to extract the downloaded file:

*Command: gunzip linux-brprinter-installer-*.*.*-*.gz*

e.g. gunzip linux-brprinter-installer-2.1.1-1.gz

Step5. Get superuser authorization with the "*su*" command or "*sudo su*"
command.

Step6. Run the tool:

*Command: bash linux-brprinter-installer-*.*.*-* Brother machine name *
e.g. bash linux-brprinter-installer-2.1.1-1 MFC-J880DW

Step7. The driver installation will start. Follow the installation screen
directions.

 When you see the message "Will you specify the DeviceURI ?",

 For USB Users: Choose N(No)
 For Network Users: Choose Y(Yes) and DeviceURI number.

The install process may take some time. Please wait until it is complete.
