So there’s something in Budgie that prevents HPlip gui from working ?
And it also seems I do not miss any package regarding qt4 - that would not work either in that Unity session.
As stated above, hplip gui works in an another session ( unity ) on that same machine and system so I don’t think packages are missing. Will check anyway.

Still the same problem. Notice also that once hplip tools is open I can no longer use the printscreen key and all interaction with Budgie shell ( panels, window controls ) become slooooow, and the icon in systray displays no menu at richt or left click. Have to use the system monitor to quit hplip.
Hmm, it seems to be an issue with the GTK2 style for Qt. Get Qt5ct (sudo apt install qt5ct), also see Can't use Qt5ct to change global application style to kvantum.
open qt5 settings from the menu, and change the style (to e.g. fusion). This will temporarily make qt5 apps use an old style. Afterwards, try again. If the issue is solved, I recommend you install Kvantum ( https://github.com/tsujan/Kvantum/tree/master/Kvantum) and choose one of those themes

Mmm… I really don’t think it’s a problem with Qt since it works in another session / another user on the same base-system but another DE ( Unity instead of Budgie ).
Maybe the problem is here : do you know if Budgie and Unity live nicely together on the same system ( but separate users ) ?
It seems to be the problem, if i understand you installed unity on UB and the application launches on UB, or do you mean you have a dualboot system with stock Ubuntu and Unity + UB?
(UB=Ubuntu Budgie)
It does seem to be a user config problem
where you can clearly see the mismatches between unity config ( ambiance theme ) and budgie.
Reason why thou shall never user different DE under one user !
And HPLiP tool box, broken.
Many users. And many systems, currently only 2, ubuntu 16.04 unity in a partition where I do my serious and important things, and UBudgie 18.04 in another partition for testing, tweaking, breaking… 3 users on each system. Therefore dual-boot.
And after all that, if I go back in my Unity session in that 18.04 system, all is fine for HPLiP tool so what’s happening here by me ? Why is it correctly displayed only in Unity, and has never been displayed correctly in Budgie, even before I install Unity ???
