HPLIP Wifi Config not working on HP Smart Tank 517

Well... I bought an HP Smart Tank 517 printer to replace an HP OfficeJet 8100 Pro.
With HPLIP 3.20.9 on Linux Mint 20 Cinnamon 64bit, I can't access the wifi configuration of SmartTank 517.
I removed the HPLIP, installed it again and can't get access.
The "HP Device Manager" panel has a message "Device is busy, powered down, or unplugged".
When executing the command "hp-wificonfig" via terminal, I see the following result:

Is there a bug in the HPLIP code in relation to this printer model?

As I have an urgency to configure, a palliative solution was to install Windows on a Virtual Machine and access the wifi settings through the VM, so it worked.
In Linux Mint, the printer detected in the printer manager is installed, configured and working. The scanner has not been tested.
