I am using HPLIP 3.15.9 on Kubuntu 15.04. It is started automatically after login and tries to add an icon to the system tray... but this does not work most times and I get an error dialog instead, that tells me HPLIP is unable to find a system tray (while I can clearly see the tray).
I found many suggetions in the web that are based on delaying the startup of HPLIP. However either they didn't work (modyfing some loop in a HPLIP script) or I could not apply them since they worked with older OS version only.
How can I solve that problem?
If delaying is a solution, where can I find the auto start entry of HPLIP? I looked in system settings of Kubuntu but the list of auto-started applications does not contain HPLIP (I suppose it is auto-started by some file based mechanism I am not aware of).
