Update the firmware
HP offers periodic printer updates, new Web Services apps, and new features to existing Web Services apps. 
Follow these steps to update the printer firmware for a single printer. When you update the firmware, Web 
Service apps will update automatically.
There are two supported methods to perform a firmware update on this printer. Use only one of the following 
methods to update the printer firmware.
Method one: Update the firmware using the control panel
Use these steps to load the firmware from the control panel (for network-connected printers only), and/or set 
the printer to automatically load future firmware updates. For USB-connected printers, skip to method two.
