Samsung Xpress M2027 WiFi Printer. Official Samsung drivers installed and printing works. Printer connected over WiFi and Google Cloud as well. Scanning doesn't work, Ubuntu does not see the scanner:
sudo sane-find-scanner does not find the printer:
# 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.
