I am quite familiar with Lightroom but I have never had this happen to me. I go to the print tab and it just says it is collecting information. It will get about half way then stops. I just did a photo shoot at a horse show this past weekend and I have several people going to be looking for their prints but I can't even print them to file. I have included a screen shot of what I am talking about. Please help me!
I thought I had it on selected photo because it was saying page 1 of 1. I could have sworn I checked the bottom to make sure that it was on the selected photo. Thank you.
Yes the "Page 1 of 1" being rather prominent on the image window would have misled me also. And I do not know why Lightroom would show that when trying to 'load' many files to the printer.
Only a longer look at your screen-clip gave me a clue.
You would have needed a good supply of paper.
