Using a USB printer connected to one computer from another computer on a LAN

[rhkramer@gmail.com]

I recently installed a new to me Brother HL-2140 printer on one of the 
computers on my LAN.  It has a USB interface.  I used the Brother installer to 
install it on that computer, and, after a few false starts, seems to be 
working fine.

I now want to try to also install the printer on another computer via the 
network (Ethernet) if possible.  (Aside: In an earlier successful iteration, I 
connected the printer to two of my computers using a USB hub and got the 
printer to work from both of those computers.)

When I run the Brother installer, I eventually get to some text like this:

Will you specify the Device URI? [Y/n] ->y

0: hp
1: smb
2: https
3: http
4: ipps
5: ipp
6: socket
7: lpd
8: beh
9: hpfax
10 (I): Specify IP address.
11 (A): Auto. (usb://dev/usblp0)
</quote>

On my first attempt at doing an install to work over the Ethernet, I chose 
option 10, and then specified my IP address (partially obfuscated below just 
for kicks), but that did not work:

<quote>
select the number of destination Device URI. 10          

 enter IP address ->192.168.n.n
lpadmin -p HL2140 -v socket://192.168.n.n -E
Test Print? [y/N] ->y

wait 5s.
lpr -P HL2140 /usr/share/cups/data/testprint
Hit Enter/Return key.
root@s19:/rhk/downloads2/printers/Brother_HL-2140/Brother#

</quote>

This did not work (the testprint was not printed).

Are any of the other options likely to work?  (I don't want to try them all to 
find out).

To repeat, the printer is a USB printer, with the Brother driver installed on 
one computer.  I am / was hoping that I could install the Brother driver on 
another computer (on my LAN) using one of the network options (see the list of 
11 choices shown above).

Thanks!
