Public bug reported:
I have used every Ubuntu version since 16.10 and on all of them my
network scanner EPSON SX525WD could be discovered out of the box.
On 22.04 the output of 'scanimage -L' is:
No scanners were identified. If you were expecting something different,
check that the scanner is plugged in, turned on and detected by the
sane-find-scanner tool (if appropriate). Please read the documentation
which came with this software (README, FAQ, manpages).
To double-check if something hadn't changed in my network, I opened a laptop
which still has Ubuntu 21.10 installed. I ran 'scanimage -L' and it shows:
device `epson2:net:192.168.8.8' is a Epson PID 085E flatbed scanner
device `airscan:w0:EPSON Epson Stylus SX525WD' is a WSD EPSON Epson Stylus
SX525WD ip=192.168.8.8
My current workaround for 22.04 is to append the line:
net 192.168.8.8
to /etc/sane.d/epson2.conf. The command 'scanimage -L' detects the scanner
(albeit no 'airscan' result shows up):
device `epson2:net:192.168.8.8' is a Epson PID 085E flatbed scanner
NOTE: I filled this bug under the 'sane-backends' package because this
form gave this error: "sane-utils" does not exist in Ubuntu
