This is one of the problems you get when you are online.
This printer ( hp deskjet 3520 all in one ) was working normally with the the windows 10 system until it says there is no driver any more .
I didn't supresse the driver and even try to re-install the the printer. But the system is adamant : no driver and no way to print any more!
In other other words:
You better buy another printer because this one is too old or you don't buy anymore our cartridge.
I think HP - if they are responsable for this problem- should be happy and proud that I can still use the 3520 model:
Buy a Hp printer, it will work untill somebody decide it is too old!
I'am afraid that one way to resolve this problem would be to finally forbid electronic signature for jet-printer's cartridge.
I finally found a way to reinstall the driver and to make it work.
Using only the windows-driver installation wasn't enough. I don't think I have made an error. I shouldn't have needed to run another software to get the printer again in the printer-choice menu. Such problem can lead to not using the printer for a long time and having the jet-printer-nozzle definitevely obstructed.
