Fixes:

- Fixed a problem where an "Invalid Credentials" error is returned for SNMPv3 I/O attempts.
- If a DHCP server responds to a REQUEST with a NAK, the server will be ignored by the Jetdirect Client until it is rebooted. The NAK is sent by a server if the client requests an address that is not supported by the server; this happens if the client has moved to a new network and attempts to renew an address from the old network.
- Implemented DHCP option 144.
- Short default TTL value caused the product to use DNS lookup cache and overlook server IP address changes. This fix involved using the TTL value provided by the DNS server instead of a fixed default.
- Certificates signed with an MD5 hash are no longer accepted by the product and many popular applications. The product will automatically replace an internally generated selfsigned MD5 identity certificate with a new self-signed SHA256 identity certificate so that it maintains compatibility with current versions of popular applications.

Determining the current version level of your firmware:

To determine the current level of firmware installed on the device:
1. Go to the printer's or MFP's control panel.
2. Press the Home button to display the Menus.
3. Use the Down arrow to select INFORMATION. Press OK.
4. Use the Down arrow to select PRINT CONFIGURATION. Press OK.
 On the printed CONFIGURATION page look in the section marked "Device Information" for the firmware date code. The firmware date code will look something like this: 20040322 07.000.0. 

Updating firmware using “HP Easy Firmware Upgrade” utility :

Important Notes:
- Do not power cycle the MFP or the PC during this process or the MFP may become unstable and or unusable.
- Please be aware that an upgrade in some circumstance may require ten minutes or more to complete.
- 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.
- Please see the section “Expected device messages during an upgrade” for more information on messages on the control panel during an upgrade.
Update process:
1. Download the HP Easy Firmware Upgrade utility file to the desktop.
2. Double click on the HP Easy Firmware Upgrade utility file. A dialog box with the name of the printer will open.
3. Use the drop down arrow to select the printer you wish to upgrade. If the device you wish to upgrade is not in the list, you must install a print driver for the device and be able print to the device with the print driver before continuing.
4. Click on the "Send Firmware" button.
5. The progress bar will begin to move to the right indicating information is being transferred.

Depending on the speed of your PC, the firmware upgrade process may or may not complete on the MFP before the progress bar on the screen completes.
7. Once the MFP reboots the firmware upgrade will be complete.
For Windows Systems: If the device is shared on the network, then the following command can be issued from a command prompt:
copy /b FILENAME \\SHARENAME\PRINTERNAME
where FILENAME is the name of the .RFU file, <SHARENAME> is the name of the machine, from which the printer is being shared, and <PRINTERNAME> is the printer's share name (do not type the angle brackets).  

Upgrade using FTP:
Using FTP: If your HP LaserJet product uses a direct network connection, you can use file transfer protocol (FTP) to update your HP LaserJet firmware. Take note of the TCP/IP address on the configuration pages.
NOTE: Make sure that the printer is not in Powersave mode. Also, make sure that any error messages are cleared from the control panel display.
1. Open a DOS command window on your computer.
2. Type ftp <TCP/IP PRINTER ADDRESS>(for example, if the TCP/IP address is 192.168.0.90, type ftp 192.168.0.90).
3. Press ENTER on the keyboard.
4. When prompted for user name and password press ENTER for each.
5. Type bin at the >prompt.
6. Press ENTER.
