thank you very much. It was the right command.

scanimage -L

but it didn’t find a scanner:

No scanners were identified


with sudo it found my printer/scanner

sudo scanimage -L
Passwort: device `hpaio:/usb/Officejet_J4500_series?serial=CN92G561F4052T' is a Hewlett-Packard Officejet_J4500_series all-in-one

"sudo sane-find-scanner"

 # No SCSI scanners found. If you expected something different, make sure that
  # you have loaded a kernel SCSI driver for your SCSI adapter.

found USB scanner (vendor=0x03f0 [HP], product=0x2a12 [Officejet J4500 series])

it found a usb scanner, but could not fetch string descriptor.

does this message say that proprietary software is the problem?

Please read the documentation
which came with this software (README, FAQ, manpages).

Can I read documentation with the terminal, having no documentation on paper? Which commands I have to use?

Kind regards

How would be the command to use libsane directly in the terminal?

I think the command to list the detected scanners is 'scanimage -L'
but my memory isn't perfect. It would be best to consult the
