Title: c480w scanner not detected anymore
Post by: agre on September 10, 2021, 05:16:29
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?

No.  Nothing in these packages has changed, unless you manually updated to a different driver version.  I suggest using
Code: [Select]
apt list --installed > ~/installedpackages.txt

on both your desktop and laptop, then using diff to identify what Ubuntu-provided packages may have been updated on one but not the other.
