Created attachment 126641 [details] Screen recording SUMMARY The "share this printer" checkbox is deactivated. However, it is possible to choose "System preferences" -> "Share printers connected to this system". This will result in enabling the checkbox "share this printer" for a half a second, then it becomes deactivated again. The terminal output may explain why, but for the average user, there's no hint why settings behave like they do. I think the checkbox should not be activated in the first place and a hint should be displayed, explaining why it's not possible to share the printer.
