PART 4: INSTALL SCANNER SERVER<\/span><\/h2>\n

In the previous part<\/a><\/strong> we configured the IP address of the Raspberry Pi. In this article, instructions are given to install scanner server software SANE. Configuration makes it accessible from the local network.<\/p>\n

23) Install internet daemon <\/span>xinetd<\/b><\/a><\/h3>\n

sudo apt-get install xinetd<\/span><\/p>\n

As a result, your has the better<\/em> intenet daemon, which makes managing sevices provided via sockets easier.<\/p>\n

24) Install Scanner server software <\/span>SANE<\/a>\u2026 <\/b>with some utilities<\/p>\n

sudo apt-get install sane-utils<\/span><\/pre>\n
The package contains sane utilities including\u00a0saned<\/strong> SANE daemon.<\/p>\n
25) Installing scanner server requires to add \/ edit new udev rule for scanner, to enable access:<\/span><\/h3>\n
sudo nano \/etc\/udev\/rules.d\/65-libsane.rulesprinter<\/span><\/pre>\n
contents of the new rule line:<\/span><\/i><\/p>\n
ACTION==\u201dadd\u201d, ENV{DEVTYPE}==\u201dusb_device\u201d, ENV{libsane_matched}==\u201dyes\u201d, RUN+=\u201d\/bin\/setfacl -m g:scanner:rw $env{DEVNAME}\u201d<\/span><\/pre>\n
26) find path of saned<\/span><\/h3>\n
which saned<\/span><\/pre>\n
Presuming, it is \/usr\/sbin\/saned , as it shoud be with Raspbian Buster Lite<\/span><\/i><\/p>\n
27) Check that <\/span>saned<\/b> is added to services<\/span><\/h3>\n
sudo cat \/etc\/services | grep sane<\/span><\/pre>\n
EXPECTED OUTPUT:<\/span><\/p>\n
sane-port<\/span> 6566\/tcp<\/span> sane saned <\/span> # SANE network scanner daemon<\/span><\/pre>\n
28) Add saned to xinetd config, so <\/span>internet daemon <\/span><\/i>will listen and provide <\/span>sane-daemon<\/span><\/i> service:<\/span><\/h3>\n
sudo nano \/etc\/xinetd.d\/sane-daemon<\/span><\/pre>\n
Add\/Edit contents to:<\/span><\/i><\/p>\n
service sane-port<\/span>\r\n{<\/span>\r\n  socket-type = stream<\/span>\r\n  server = \/usr\/sbin\/saned<\/span>\r\n  protocol = tcp<\/span>\r\n  user = saned<\/span>\r\n  group = saned<\/span>\r\n  wait = no<\/span>\r\n  disable = no<\/span>\r\n}<\/span><\/pre>\n
29) Edit sane daemon config, adding your current wlan subnet as permitted.<\/span><\/h3>\n
sudo nano \/etc\/sane.d\/saned.conf\u00a0\r\n<\/span># Leaving only uncommented line as<\/span>\r\n192.168.1.0\/24<\/span><\/pre>\n
30) Add user lp to saned group\u00a0<\/span><\/h3>\n
sudo adduser saned lp<\/span><\/pre>\n
31) Enable saned socket to receive and send<\/span><\/h3>\n
sudo systemctl enable saned.socket
\n<\/span>32) Check saned socket status<\/span><\/p>\n
sudo systemctl status saned.socket<\/span><\/pre>\n
33) Get free client software: SwingSane<\/span><\/h3>\n
I recommend SwingSane.<\/a> It is quite functional. Eve so, on Windows the custom scanning settings had to be used always <\/em>to get good scanning results.<\/p>\n

Working Swing Sane Custom Settings<\/figcaption><\/figure>\n
Install SwingSane to a client computer. Then, configure it by adding new scanner by IP address. In this point, you can give it any name you want. The Remote Address<\/em> is the address of the Raspberry Pi, and the SANE port number is 6566.\u00a0<\/span><\/p>\n
\"\"<\/p>\n
34) Do a test scan<\/span><\/h3>\n
As a result, of the installs and configuration, you should have now a printer – scanner with a WiFi connection, that can be reached over the wireless local area network.<\/p>\n
I didn’t make this all up by myself. Some partial instructions were helpful. Therefore, I give them credit and backlinks:<\/span><\/p>\n
