HP Officejet Pro 6830 can not be connected via USB

[Josy]

After updating to Ubuntu 20.04. I was unable to print via my HP Officejet Pro 6830 printer via WLAN and via USB.

I managed to get the printer running via WLAN by going to CUPS (In Browser: http://localhost:631), deleting the stalled printer jobs and deleting the printers via cups.

Afterwards I added the printer connected via WLAN using the command-line tool hp-setup. This was successfull.
However, when adding the same printer with hp-setup connected via USB, the connection failed with the error message "Unable to communicate with the device. Please check the device and try again.".
The device is connected to my PC via WLAN and USB. There is no problem.

I had expected that the usb printer driver for my hp Officejet Pro 6830 got installed and afterwards successfull printing is possible.
