Impressora Wi-Fi Samsung Xpress M2027. Drivers oficiais da Samsung instalados e impressão funciona. Impressora conectada via WiFi e Google Cloud também. A digitalização não funciona, o Ubuntu não vê o scanner:
sudo sane-find-scanner não encontra a impressora:
# sane-find-scanner will now attempt to detect your scanner. If the
# result is different from what you expected, first make sure your
# scanner is powered up and properly connected to your computer.
# No SCSI scanners found. If you expected something different, make sure that
# you have loaded a kernel SCSI driver for your SCSI adapter.
# No USB scanners found. If you expected something different, make sure that
# you have loaded a kernel driver for your USB host controller and have setup
# the USB system correctly. See man sane-usb for details.
# Not checking for parallel port scanners.
# Most Scanners connected to the parallel port or other proprietary ports
# can't be detected by this program.

Você precisa dos drivers Samsung da HP (a HP comprou a linha de impressoras Samsung, eu acho). Outra alternativa é instalar os drivers originais da Samsung ou usar o repositório SULDR:https://www.bchemnet.com/suldr/
