Which one, Bedrock or Java?
For Bedrock there is an unofficial launcher: https://flathub.org/apps/io.mrarm.mcpelauncher (Disclaimer: Never tried it)
For Java there is the offical launcher: https://flathub.org/apps/com.mojang.Minecraft
Alternatively, for Java, there are also the much better unofficial launchers like Prism: https://flathub.org/apps/org.prismlauncher.PrismLauncher
I assume you tried adding a new printer through KDE? There’s usually no driver needed if all you need to do is simply print/scan.
Does it fail with both options?
