I have several spreadsheets which refuse to print to near the edge of the
paper, no matter how I alter the various print settings. See the attached
screenshot:

Notice how the printed area is about 2 inches from the left and right
margins. On the Page tab I have got ample "Fit to" pages wide and tall.

Why is this happening?

Thanks in advance.
