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
Note
TCP/IP configuration cannot be disabled on the HP Color LaserJet 5550 series printer.
To disable IPX/SPX
Note
Do not disable this protocol if Windows 95/98, Windows NT, ME, 2000, and XP users will be
printing to the printer.
