I have an HP Laserjet Pro MFP m130fn all-in-one printer. Connected with USB.
scanimage -L info: device `hpaio:/usb/HP_LaserJet_MFP_M129-M134?serial=VNH7C06822' is a Hewlett-Packard HP_LaserJet_MFP_M129-M134 all-in-one airscan-discover: [devices]
I just installed Ubuntu 21.04. Even though I can print with that device, I can not scan with it. After launching the app "Document Scanner" my printer appears in the drop-down menu and "Ready to scan" shows inside the window. After clicking on the green button "Scan" I am getting an error window with the message "Failed to scan - Unable to connect to scanner".
