Hello. I'ld like to improve scanner quality using the scan-chrome-app.
I see in a post from you that we could use scanimage with the --resolution. But how to set the resolution when using your app ?

Can you confirm that this only supports network scanners and does not work with USB scanners? Thanks!

When trying to launch the app, no window opens. Instead, this message appears in the developer console:

HTML Imports is deprecated and has now been removed as of M80. See https://www.chromestatus.com/features/5144752345317376 and https://developers.google.com/web/updates/2019/07/web-components-time-to-upgrade for more details.

That second link mentions that there might be a polyfill that would get this working again.

We have been using older versions of the CanoScan LiDE family without issue but upon purchasing the latest version, 120, we can no longer see the scanner.

A quick google saw a post suggesting that for the scanner to work under Linux a later version of Sane is required (1.0.27). Not sure if this is baked into your software but presumably ChromeOS itself?
(I also posted this comment on the app itself in the store)
