How do I enable HP Web Services on the printer?
Open the HP Embedded Web Server (EWS) by viewing the IP address on the control-panel display and entering it in a Web browser, then click the HP Web Services tab and select the option to enable Web Services. After enabling, go to www.hpconnected.com or www.hp.com/go/eprintcenter to create an HP ePrint account and complete setup, which may take several minutes.
