[sane-devel] epson es-600c parrallel configuration

[Karl Heinz Kremer]

You have to write a wrapper application, that is then run as suid 
root,which in turn calls (a non-suid root) xscanimage.

The other option is to use the net backend. There are probably a number 
of instructions in the email archives.
