Why the downvote?

one can never know without trying so if a plugin is not free in linux what happens then? Do we get some error message with e.g. a URL to paypal to pay for example?

Where can I get sane-airscan? Do I need anything extra to print over wifi?

I installed the same file from the URL in my post. It is the exact file as in your post. I installed it and did not work. Then I noticed you mention "Reboot". Then after reboot, it worked. I didn't expect that reboot would be required! How come?

@music2myear: I have connected it with a cable and I can see it reported but it does not work. I see a list of Epson printers available but I don't know which one to choose so I found those I mention in the post

for the record I found support.google.com/chrome/thread/170130544/…

But there is no possibility that if not merged automatically after signing out, the passwords etc of the original anonymous usages are lost right?

If I sign in is there a way to merge the data from the signed in account with the signed account?

The csv can it be imported again? Also If one signs in, would the all the data saved so far when using with no account be merged with the account?
