I have the worksheet in which all the margines are set to 0 (i.e. left, top,
bottom,right,header,footer).
Then I apply the folloing settings
FormatStyleModifyFont select Courier New, Reqular, 10.
FilePage SetupPaper size : A4 and Print quality : 600 dpi.

Now my worksheet contain 73rows/page.
Each row has 13.50 points height. so page height is 73*13.50 = 985.5 points
But the standard A4 paper size height is 842 points.

So how the excel fits the 73 rows of each height 13.5 points?
