I am not sure if this is the correct product. I am referring to the default Plasma printing tray icon. I have this setup: an HP Officejet Printer connected via LAN which is located in another room. When I print to this printer while it is still offline, there is no notification about it. It would be better to get notified right way instead of realizing it only when arriving in the other room. :) I will attach a screenshot of the notification I get when I send something to the printer regardless if online or offline.
