I use Gentoo and they don't have a saned initscript in /etc/init.d for some reason. > Note that with saned your scan server still communicates with a local > USB device. ?That is, saned is the scan server's SANE frontend of > choice. ?The client then uses the SANE net backend (via the client's > SANE frontend of choice) to talk to the server. > >> I noticed that /etc/sane.d/* has network ability, but that's for >> communicating with a network scanner directly, right? > > Depends on what * stands for ;-) How about /etc/sane.d/epkowa.conf and /etc/sane.d/epson2.conf? >> I tried to set up network scanning with epkowa and my Epson Artisan >> 710 but I couldn't get it to work, I think because I don't know which >> port to define on the scanner's IP. ?Does anyone have any suggestions >> for that? > > First of all, you need the (binary-only, non-free) iscan-network-nt > package installed. ?Second, you need to follow the instructions in > /etc/sane.d/epkowa.conf WRT configuring a network scanner. ?There is no > need to specify a port number, the default (1865) should do. ?Follow the > instructions in the product manual to determine/assign the IP address of > the device. Is iscan-network-nt available for free? I had assumed iscan-network-nt was included in Gentoo's iscan package but I must have been wrong. Does anbody here know if there is an ebuild available?

Could the epson2 backend work via "net" even though the Artisan 710 is listed as unsupported on the SANE website? - Grant
