print is off center (even in preview) and can't center
Printing from Photoshop had been going fine but now when the print setup window comes up the "canvas" (the white rectangle on the diagonal lined background) is itself off center. And sure enough my prints are, too. What can I do to fix this?
In the screenshot is my attempt to print a 7.5" x 10" image on a 8.5" x 11" paper.
