@Terry7979, Welcome to the HP Support Community!

An E0 error indicates an unusable cartridge.

This condition occurs when at least one ink cartridge needs attention, is faulty, incorrect, missing, damaged, or incompatible. Reseat both ink cartridges, clean the ink cartridge contacts, restart the printer, and replace one or both ink cartridges if necessary.

Refer to this document to know how to connect the printer to the wireless network - Connecting an HP Printer Using Wi-Fi Protected Setup (WPS)

Other methods can be found on - HP printer setup (wireless network)

• Make sure the printer and the PC are connected to the same wireless network. Either 2.4 or 5GHz network.
• If you have a Dual-band router and both 2.4GHz and 5GHz networks share the same name/SSID, the printer will not be able to connect to the network. In this case, contact your Internet service provider to assign different names to both the networks
