Disabling network protocols (optional)

By factory default, all supported network protocols are enabled. Disabling unused protocols has the following benefits:

  • decreases printer-generated network traffic

  • prevents unauthorized users from printing to the printer

  • provides only pertinent information on the configuration page

  • allows the printer control panel to display protocol-specific error and warning messages


TCP/IP configuration should not be disabled on the HP Color LaserJet 3550 printer. If you disable TCP/IP, you will lose the connection to the printer’s embedded Web server page.
