locate serial number

[robertods100]

I am trying to add my printer to the hp devices on the HP Support Assistant.

As my device has not been automatically detected, I am trying to add it manually.

To do so, the HSA asks for the product serial number.

I was not able to find it.

Can you tell me where I can find it, so that I can add my device to the HSA software?

Thanks.
