Samsung SL-C430W & Debian 10 USB, Ethernet and Wireless test page won't print.

[globetrotterdk]

Hi, new to the forum. This is my first post. I am experiencing a problem with a fresh vanilla Debian Buster (Cinnamon) install from yesterday. When connected by USB to my computer, printing a test page from my Samsung SL-C430W printer returns an SPL error message - error code 11-1114. With the printer connected either by an Ethernet cable or by WiFi, I get the message:

Processing - Unable to locate printer "SEC8425197B7B79.local". - "Is your printer connected?"

Nothing happens further and my printer at this point is about as useful as a large rock sitting on my desk.

No firewall, so that isn't the problem...

It appears that the Debian CUPS team backported a problematic change introduced in CUPS 2.2.11 to 2.2.10 (-4 and later).  You are running into the issue from this bug:
https://github.com/apple/cups/issues/5562

The bug is fixed in 2.2.12 and 2.3.x, but that particular fix was not backported by Debian to 2.2.10.  You can try opening a bug against the Debian package and see if the relevant committ can be backported.  Otherwise you will need to revert to an earlier snapshot of CUPS (2.2.10-3 or earlier) or manually update to 2.2.12.

Many thanks for the reply. It sounds to me that the easiest (and quickest) thing to do would be to manually update to cups version 2.2.12. Spent hours on trying to find a 2.2.12 package available from Debian, but nothing seems to be available. What do I need to do?

You can find every Debian package ever released here:
https://snapshot.debian.org/

You would need to download the 2.2.12-2 packages for whichever cups* packages that you have installed, then dpkg -i *.deb.  Note that because 2.2.12 was never released for Debian 10 (it only briefly existed in unstable/testing), there may have been a dependency change that will cause problems.  If that occurs, you are probably better off downgrading to 2.2.10-3 using the same process, then pinning those packages so they do not update.
