Ever since the HP driver issue with MacOS catalina, which forced me to uninstall and reinstall new HP drivers my Envy 7640 powers off after a few minutes and will not respond to its power button or to print requests. I have to unplug it to make it work again. It is hardwired to my network switch, is using DHCP to get an IP address, and has the latest firmware. Everything works as before when it is awake. None of the procedures offered here work. Auto-off is disabled since the printer is connected to a wired network. The HP support site is useless since the printer is out of warranty. I use instant ink, but I will not be coming back if HP abandons me here.
