I have Debian 10 with GNOME, and the printer/scanner is an HP Color LaserJet Pro MFP M181fw.
I added this printer using the "graphical mode" (not using command lines). The printer works. In the setup I see both printer and scanner but when I try to use the scanner the message "impossible to find the scanner" appears. (I don't know if the exact English translation is this one; I see the message in Italian.)
How can I use the scanner?
