How do I disable the Epson Firmware update on MacBook Pro?

the printer wouldn't print using my generic ink cartridges, saying it couldn't read them.

Some printer companies may block generics cartridges. You probably need to chat with Epson support, or try a different brand of generic.

I’ve looked online at the Epson site and there are no software downloads.

Thanks for that — the Epson WF-2850 is notorious for firmware updates that block third-party (non-Epson) cartridges.

Unfortunately, with the Epson WF-2850, once you install a firmware update, you can't disable or roll it back through Epson's official software or settings. These updates often specifically target the use of third-party ink cartridges — even some older Epson-branded ones may stop working.

Since even your Epson-brand cartridges aren’t working, it may be worth contacting Epson directly. If the firmware update caused the issue, they may offer a replacement or repair — especially if it’s recent.

Agreed!

I doubt there is away to undo a firmware update.:(

What is the Epson printer model involved, please?
