Latest firmware installed?
Have you unplugged and let it sit it for 10 minutes?
That was the recommended fix when our Epson started printing VERY slowly after a Win10 update....
Good luck with it gronk....
Firmware ? Dunno...I uninstalled it off the computer and reinstalled it with drivers from the HP site.
I unplugged it and let it sit for hours.
I can make it print, but not the normal way......I can make it scan to computer, but not the normal way.
I can deposit it into the bin if it ceases to work at all !!
