WOW! Do I feel foolish. I don't ever remember seeing that and if I did, I don't remember changing it in all the updates that preceded 9.1. I opened LR, went to the print module and sure enough all was selected. I made the change and the image I had selected was front and centre. I'll try making a print tomorrow but I'm sure that fixed my issue. Thank you Rich.
Now I'll mention one other issue that I noticed when I launched LR. When I clicked on the icon to launch LR, it opened in the usual way, the splash screen appeared and then the screen behind it, then the splash went away. The usual sequence. Then a few seconds later, the splash screen appeared again, then clicked off.
