Fields not entirely within the printable area of a form layout will not print

You must position every field and column in your custom form design to appear entirely within the printable area of the form. (This area is displayed in solid white in the layout area of the Customize window.) Fields that even slightly overrun the printable area of the layout will not appear at all on your printed form, even though they remain visible in the form's Customize window.

New data columns may be positioned slightly off the right side of the printable area when you first add them. If this is the case, you may have to move or adjust the size of existing columns to ensure that the new column is entirely within the printable area of the form.
