I've since discovered that if, when in preview mode, I use the buttons on layout to print from preview it does the same thing. It will only set up to print in portrait mode, but if I hit button save as pdf and then preview and print the pdf it works correctly. I don't know.
Everything is working now. I'm not sure what happened. My guess is, the printer driver update that downloaded on software update about a week ago didn't get installed correctly and perhaps was causing conflict. After I powered everything down, including unplugging the printer and then starting up again, not only is conflict resolved but printer has never been so fast. Hah, emotions went from; Oh no, what now, to Cool, that works!
