Public bug reported:
I am running Kubuntu 20.04 with Ubuntu Studio on an HP zbook 15 G3. My
printer / scanner is an HP Envy 5542.
Scanning at the defaults, text 150 dpi / image 300 dpi works 'out of the
box'.
Changing resolution to 600 / 1200 dpi sets the scanner working (shows
"Scanning..." in the display, making noises and moving the scanning
parts), but fails.
simple-scan gives the error message "Failed to scan. Unable to start scan".
skanlite fails with "Invalid argument".
On my previous system, Ubuntu Studio (xubuntu) 18.04, all available
resolutions worked with the same printer, so I'm sure the scanner
supports the tested resolutions.
