This page describes how to enable Network Scanning using a USB scanner or multi-function printer using S.A.N.E. (Scan Access Now Easy).

Make sure you've got SANE supported scanner.

opkg install sane-frontends dbus xinetd

Create file /opt/etc/xinetd.d/saned and put the following content:

service saned
{
type = UNLISTED
port = 6566
socket_type = stream
server = /opt/sbin/saned
protocol = tcp
user = root
group = root
wait = no
disable = no  
}

Edit file /opt/etc/sane.d/saned.conf and add your subnet to allow access, for example: 192.168.1.0/24. Reboot device and make sure that dbus and xinetd are running (this step might not be required if you know how to start the services manually from /opt/etc/init.d).

For HP scanner:

opkg --force-overwrite install hplip

Type: scanimage -L, your device should be displayed. Type: scanimage --test, your device should start testing and display status.

• Install the sane package. This changes by distribution
• Edit file /etc/sane.d/net.conf and add the ip or hostname of the router
• Test the same way with the scanimage utility

• Download SaneTwain
• On start-up put the router's ip/host
