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.
