It was an ethernet patch cable that the tech had suggested. I can't remember if I decided not to worry about it due to cost, or lack of availability for my printer. Either way, moving forward, I'll just turn the printer off when not in use. As I'm retired, I don't print a lot these days and recycle the paper as the message is at the top of the page so when I'm just printing something for myself I just use the reverse side.
Thanks so much everyone.
