Hi @David-TP, Sorry for the delayed response. I'm using the official driver from Epson webpage, and just the default setup from macOS 26. Printing works again when disabling the Intrusion Prevention...

Hi @David-TP, I've noticed the exact same behavior with an Epson L555 but instead of a Deco I'm using an Archer AX6000. The Intrusion Prevention System is also blocking connection with the printer.
