Have you chosen the right paper size in your printer driver?
Have you set the cell size appropriately in Lightroom?
Is this a new problem that just began happening?
I was in the middle of repeated print jobs, same cell size,
same paper size, and this suddenly happened. I double checked
these issues anyway and everything is correct.
I'm using Lightroom 5, and don't have any problems like that when I print. About the only thing I can suggest would be for you to delete the preferences file. This seems to be a catchall that fixes a lot of weird problems that come up. I don't know if it would help in your case, but it might be worth a try.
Very kind of you to respond. Came back from running errands, began working on a new image
thought I would try printing and photo came out perfect. Don't know why. Thank you for the tip
about the preferences file for future troubleshooting.
