Enable saned on terminal

Edit /opt/ltsp/i386/etc/lts.conf and add XINETD_SERVICES = "saned" to the default or relevant terminal section
Restart the terminal
Run scanimage -L on workstation shell to verify that scanner has been detected

top

Usage

Physically plug the scanner into the terminal using USB or parallel port.
Edit /etc/sane.d/net.conf and add the hostname or address of client running saned
Use xsane, OpenOffice.org, GIMP, or any other scanner-aware application, as they should now list the scanner.

Alternative to net.conf

If you do not wish to add the host to net.conf (as shown above) then you can run the following:

$ SANE_NET_HOSTS=`echo $DISPLAY | cut -d: -f1`
$ export SANE_NET_HOSTS

This will only work for the life of the terminal window - so you will need to run the application from the command line. Alternatively add this to a script that does the scanning.
