Here are the steps to installing and accessing a network scanner from Ubuntu desktop client. It is assumed that the network scanner server is already up and running.
1) Let us first check whether there is a scanner available on our Ubuntu client host. Without any prior setup, you will see the message saying that "No scanners were identified."
$ scanimage -L
2) Now we need to enable saned daemon which comes pre-installed on Ubuntu desktop. To enable it, we need to edit the /etc/default/saned file, and set the RUN variable to yes:
$ sudo vim /etc/default/saned
4) Restart saned:
$ sudo service saned restart5) Let's see if the scanner is available now:
Now we can open "Simple Scan" (or other scanning utility) and start scanning documents. We can rotate, crop, and save the resulting image:
Note: most generic print servers do not support this feature.
