--- Comment #6 from Ben <benthem...@gmx.net> --- Problem 1 My problem, which I have explained in the title, is gone. I already said it in the comment. However, if you want to see what went wrong during the upgrade process from 5.17.2 to 5.17.3, you have the choice. Problem 2 Because something went wrong. There may still be wrong rights. I told I cannot set a new printer or printer driver. So I cannot change the printer in the configuration. It was the update process. For me as a user it's the same. Printing and Printer configuration went wrong. In one case I saw message "Filter fails" but print works right. I know in most cases it's a cups problem. But the same software packages (plasma-desktop) produces no issue in KDE neon. This problem I saw only in Kubuntu 19.10 with backports. Same Desktop. Now Plasma 5.17.4. So, logically, the problem can be found in the backports. For the programmers behind there may be two problems. Or much more. I don't know. Again: I can only say that the printing fails. If the original driver from 2012 runs with KDE 4 + 5, and again with neon-user-20191128-1117.iso than it's not a cups problem. It comes from the update process. This is the only reason why I wrote this bug report. It is absolutely impossible for me to be the only user experiencing this issue. A really flawed mistake for a user he can not fix himself. I can not know which packages or modules are interlinked and which works together with another. The malfunction comes from the update process. -- You are receiving this mail because: You are watching all bug changes.
