Meanwhile I changed cable connected to the printer and I got another output:

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). ------------------------------------------------------------------ This looks better, but scanner still wasn't found.
