Hi, I'm looking for an old version of the firmware for my HP 8715 printer so I can continue using non-original cartridges.
Old firmwares have been removed from official support page.
I kindly ask you for a link so I can recover them.

Hi @GWelldone,
Welcome to the HP Support Community.
I'd be happy to help you!
I am afraid that the firmware downgrade is possible for any OS.
However, You may refill your cartridges or use remanufactured cartridges, but you may run into problems. HP will not guarantee the functionality of those ink cartridges.
There are many cartridges in the market which is refilled and sometimes the chip is not configured to work with the printer. You need to contact the cartridge manufacturer and find out why it's not working. Try a different cartridge supplier and check if that works.
Hope this helps!
