"Couldn't recognize IPv4 of scanner 'smfp:usb;04E8;3419;8P54BAIQ223032B.'."

I'm trying to set up a Raspberry Pi as a printer/scanner server for my network-unaware Samsung SCX-4521F.

I've installed suld-driver2-1.00.06 and suld-scantopc.  "scanimage-L" seems to identify the scanner:

# scanimage -L
device `smfp:usb;04E8;3419;8P54BAIQ223032B.' is a SAMSUNG SCX-4x21 Series on USB Scanner

When I run samsungScannerServer.py though, the script dies with this message:

INFO:stderr:Couldn't recognize IPv4 of scanner 'smfp:usb;04E8;3419;8P54BAIQ223032B.'.

This is not entirely unexpected, because the machine is connected via USB.  What can I do to get around this?

A post in another thread indicates that support for the SCX-4521F is not likely:

The scanerServer is for scanners connected via network only so it will not work if you connect your scanner via USB.

Supporting a USB connected scanner will require the reverse-engineering of the USB protocol. If your scanner just have a key to trigger the scan then maybe the following tool works for you: http://scanbuttond.sourceforge.net/ There is an (old) tutorial at http://archive09.linux.com/feature/59138

and unfortunately the abandoned scanbuttond project doesn't support Samsung units.
