Thanks for your response. Zoom to fill is checked and all margins set at the lowest setting allowed resulting in an image size of 4.75" x 6.76". Since it is set zoom to fill, and since those same settings worked for every other of over 30 images, I'm baffled by this. Turning off zoom to fill would seem a likely solution except for the fact that the preview image LR displays clearly shows the full signature. Moreover, if I uncheck zoom to fill and/or change margins, I will no longer get a nominal 5x7 print. Every other time I've adjusted zoom or margins, the preview display follows to portray the change. I can't see how anything I've done makes a difference but always willing to be enlightened.
