WINS: If you have a Dynamic Host Configuration Protocol (DHCP) server
on your network, the printer automatically obtains its IP address from that
server and registers its name with any RFC 1001 and 1002-compliant
dynamic name services as long as a WINS server IP address has been
specified.

IPP: Internet Printing Protocol (IPP) is a standard network protocol for

access control, authentication, and encryption, allowing for more secure
printing.

Clean the printhead
If your printed output is streaked or has any incorrect or missing colors, the printhead
might need to be cleaned.
If print quality still seems poor after cleaning, try aligning the printer. If print quality
problems persist after cleaning and aligning, contact HP support. For more information,
see HP support.
