Well, my saga continues.
As soon as I deleted the HP app, my Epson printer printed that message 3 times on the same page.
I turned off the printer and went into another room.
Came back and there was a page of paper sticking out from my turned-off printer with the same message.
Next day, I switched the usb printer cable to a different port and am now back to 1 time a day, between 6 and 6:15 pm EST.
