Hello all, and thanks again to everybody who answered. Eventually, due
to unavailability of other models both on Amazon and nearby stores,
and other reasons not all relevant here, I have ended up with an Epson
XP-4100

The printer part was recognized without problems by Ubuntu 20.04, the
scanner not at all. I asked on the SANE developers list, and thanks to
their help I managed to make the scanner work... but in doing so I
"lost" the printer. Now I have two distinct printers in the Ubuntu
settings panel, instead of one, but when I print a test page from
there, or from the CUPS web interface, I get "printing completed" but
nothing at all happens in the printer. I have already posted all details
of that problem, and of how I made the scanner work here:

https://alioth-lists.debian.net/pipermail/sane-devel/2020-November/038507.html

so I will not repeat them here. Any suggestion on how to debug the
printer issue is obviously welcome.

TIA,
Marco
