Code Select
Description: Ubuntu 20.04.3 LTS
Release: 20.04
Codename: focal
I used the c480w scanning feature via network quite a lot but it stopped working on my desktop.
Network discovery is showing the printer:
Code Select
$ /opt/Samsung/mfp/bin/netdiscovery -s --snmp
# DEBUG: Network printers discovery utility
ip: 192.168.178.49 slp: 0,0,0,0 snmp: 1,1,0 vendor: Samsung dsc: "C48x Series"
But sane doesn't (it is showing on the laptop - also Kubuntu):
Code Select
$ sudo sane-find-scanner
# 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.
Any idea what changed?
