Hello, I’m Virginia, I have 20 years of expertise in fixing my own & friends’ PC problems.
Sorry to hear you’re experiencing problems.
When installing the printer’s drivers you’’l have the option to connect via cable or Wi-Fi, which did you choose? If Wi-Fi ensure the entered SSID & passphrase are correct.
if cable then you may have to rerun setup to choose Wi-Fi in order for the printer to register on the network.
