From quick look this might be problem in indicator-application...
Looks like hplip trayicon first is created without menu, "/NO_DBUSMENU" is set as "Menu" for status notifier item. Then it is updated to correct menu path, but indicator does not recreate menu.
As workaround use `systemctl --user restart indicator-application.service` to restart indicator application. Then it will pickup / use correct menu path.

D-Bus menu is created only when application is added: /git.launchpad. net/ubuntu/ +source/ indicator- application/ tree/src/ indicator- application. c#n555
