My printer Officejet 4620 never had problems and it is still working good.
However, after installing last update of Win10 (version 1703, build 15063.674) the icon on desktop is no more working.
This icon should open "HP Printer Assistant" with status of ink and the choice of starting scanning, printing, etc.
After double clic on the icon, the usual smal circle opens for a few seconds and then disappears, nothing happens.
I have reinstalled the driver (OJ4620_1315-1) several times, but without success.
Now the printer works by using its panel, or using the instruction "Print" on the different documents, but I have no information on it.
Thanks to those who could help me.
