Downgrade Designjet T120 and T520 Firmware April 04 2024, 0 Comments

I offer a .rar file to downgrade your Designjet T120 or T520 firmware.

The feature of an older version of the firmware is that it allows you to use third-party inks and printheads. HP prohibited the use of third-party consumables with their latest firmware update. For more info: fixed@designjetpartsfast.com
