Printer Setup, Software & Drivers

I have a HP Envy 4520 connected on my WiFi (2.4GHz), and my laptop (Windows 10) connected on the same WiFi. I have disabled the firewall on my laptop.
Yet, I cannot fully install the HP device (i.e. the printer AND the scanner functions).

First, I try the Install software from HP with the drivers. When I end up on the window Connection Options, I select "Automatic Setup".

On the next window, I select "I see the status is Connected and the signal strength" and I enter the IP address of the printer.

I end up on a window named "Unable to Find the Device".

Everything seems correct so I click "Search" and then I end up on the same page. And so on.

So I launch HP Print and Scan Doctor 5.7.2. It searches for products but then the window shows nothing, my product is not listed.

So I try installing the printer directly through the Windows function "Add a printer or scanner". It works in some way: the device is added to my list of printers and scanners, BUT only the printer function works, the scanner function does not work.

So I go back to HP Print and Scan Doctor. It now says that the "HP Envy 4520 Series" product is visible from my computer, but when I click 'Next", I get the error "Failed to communicate with your selected product".

Why the HP programs do not detect the HP printer? How do I fix this issue and install the device correctly (i.e. with the scanner function)?

Note that when I connect the printer to my computer via USB, everything works perfectly, the Driver Installer detects the device and so does HP Print and Scan Doctor.
