The sheet report's Print: line — what differs from Excel's defaults — or null when nothing
does.
Parameters
sheet: IWorksheet
Returns string|null
Remarks
Built from the settings a reader acts on, not from toJSON(): a file routinely carries print
state nobody chose (the printer's resolution, its opaque settings, the automatic breaks Excel
last paginated with), and a sheet whose only print state is that is a default sheet.
