The Department of my spouse is now using Brother over HP 
printer/scanners.  To duplicate what she has in her office, we purchased 
the same machine for our use, a Brother dcpl2540dw.  I installed the 
Brother proprietary Linux drivers, and using the SL 7 printer 
configuration application (CUPS based), had no issues with getting the 
printer to print a test page using our home IEEE 802.11 network.   
However, it appears that the dcpl2540dw will not scan to a USB device, 
unlike the HP unit, but only to a computer on a network.  Has anyone 
been able to get the Brother dcpl2540dw to operate as a network scanner?

The computer in her office has the printer physically near her office 
tower workstation (not a laptop), and is connected USB. Thus, there is 
no network connection to the printer in her office, unlike at home.  
However, in neither case have I been able to get the scanning 
functionality to work.

Also, what application does one use to accept the scan or to allow the 
scanner to produce a .pdf file on the target computer? I simply scanned 
to a MS FAT file system USB memory stick on the HP unit, but evidently 
the Brother does not have this capability. Once on a memory stick, the 
PDF file easily could be accessed on a SL7 system.

I have found a systems tool that is claimed to simplify the process and 
not depend upon updates from Brother as new releases of Linux appear:

Has anyone used this application?  If so, any comments?  Is there any 
GPL, etc., application with similar functionality?

Thanks for any information.
