Hi,

You cannot remove Dynamic Security for the HP Officejet Pro 7740 printer:

 

note: This printer is enabled with dynamic security. It is intended to be used only with cartridges with an original HP chip. Ink cartridges using a non-HP chip may not work, and those that work today may not work in the future. 
For more information see Dynamic Security Enabled Printers.

You may use Non-Genuine ink cartridges, but only a such with an original HP security chip or unmodified HP electronic circuitry.

I have seen comments (not here) that suggest the firmware can be downgraded to such as without this update but can't seem to find the firmware.
