Plugin log out the user if there is some time of inactvity or after a print job. The time of inactivity and also the print status for the logout can be adjusted.
Plugin starts a countdown timer after login and if the timer is count to zero, the user is automatically logged out. The timer is restarted each time a user clicks on "something" like a tab-change.
This plugin, as well as my other plugins were developed in my spare time. If you like it, I would be thankful about a cup of coffee :)
