This document is aimed at how to perform HP Printer Firmware upgrades using an USB port to a Windows PC, when one of the following situations exists:

  • Upgrading printers with no Network option.
  • When a Resend RFU message appears while upgrading the firmware through network ports.


  1. Download the HP Printer Firmware from the respective products from Click here to download the appropriate firmware from .

  2. Save the firmware file to the desired location on the PC. Firmware files would be in either .exe or .zip format.

  3. Unzip or execute the downloaded firmware file, while doing this make a note of the location the files are getting stored or unziped.

After this is done we need to know the name of the computer the printer is connected to, and we also need to enable printer sharing. The following steps shows how to find the name of the computer, share the printer, and upgrade the printer firmware, using a USB port for Windows XP.

How to find out the name of your computer:

  2. You will find your computer’s name in the right window-pane next to System Name .

  3. Write down this name, because it will be needed later.

How to share the connected printer:

  2. Right-click the printer you need to send the upgrade to, then choose Sharing

  3. Choose the radio button labeled Share this printer .

  4. Type a name for the share. Make it short and easy to remember.

  5. Click Apply and write down the share name, as it will be needed later.

    For example: “HP Color LaserJet Printer”

How to send the firmware upgrade using a USB connection:

  1. Open a DOS Command Prompt (in Windows NT® 4.0, 2000, or XP, click Start, Run , then type CMD and press OK , or in Windows 9x click Start, Programs, Accessories , and then click MSDOS Prompt .) and locate the directory where you saved the firmware file.

  2. Type: copy /b C:\file name \\computer name\share name

    For example:

  3. Press Enter .

NOTE: When the upgrade process has completed the LaserJet will reboot. Once the printer is back online, print a Configuration Page and verify that the new firmware has been installed.
