Introduction
Similar to service packs for operating systems, HP provides rmware updates for printers to help address any
known issues and add new features throughout the support life of the printer.
To make sure the printer is up to date, HP recommends updating the rmware for HP Enterprise and HP
Managed printers. See Applicable printers on page 300.
Before you begin
Before upgrading rmware, make sure that any solutions used with the HP printer(s) will support the new
rmware version and review these requirements:
NOTE: Enhanced security features and settings implemented in recent rmware releases coupled with device
resets might block the installation of some solutions. For more information, see the white paper Overview of
Secure by Default Settings for Solutions.
● A rmware update requires a network connection or USB ash drive, and internet access.
● This printer cannot be updated using FTP, LPR, or Port 9100 methods.
● If you have a third-party solution, contact the vendor to make sure that the latest rmware version is
compatible with the solution.
NOTE: If device resets are performed as part of the update process, these solutions might need to be
reinstalled or recongured.
● If a solution also needs to be updated to support the new rmware, HP recommends updating the solution
rst before updating the printer.
● A rmware update can require 10 to 30 minutes or more depending on the computer speed and
connection type.
● Remote rmware downgrades are not supported. For more information, see About rmware downgrades
on page 300.
● The steps in this document apply to only to HP Enterprise and HP Managed printers. See Applicable printers
on page 300.
