A print came out with a 3/8 inch wide cyan strip in the white border on the long dimension on one side.

Problem: A print made via the 16-bit plug-in--of an image with with wide white borders around the image area--came out with 3/8 inch cyan stripe right down the middle of one of the long-dimension borders.

Workaround: Turning the printer off briefly and then back on again cleared up the problem, at least temporarily.
