This tab provides the following items:

| **Item** | **Description** |
| ---- | ----------- |
| Top | Set the top margin (between the top of the page and the top of the header) for the printed page. |
| Left | Set the left margin for the printed page. |
| Right | Set the right margin for the printed page. |
| Bottom | Set the bottom margin (between the bottom of the page and the bottom of the footer) for the printed page. |
| Header | Set the header margin (between the bottom of the header and the top of the contents) for the printed page. |
| Footer | Set the footer margin (between the top of the footer and the bottom of the contents) for the printed page. |
| Center on page | Set the data to be centered on the page within the margins by selecting the **Vertically** check box, the **Horizontally** check box, or both. |

The units of measure are inches, so 3/4 of an inch would be 0.75. For a 1-inch margin, type in 1 or 1.0.
For more information on these settings, refer to the members of the [PrintMargin](/spreadnet/api/latest/online-win/FarPoint.Win.Spread/FarPoint.Win.Spread.PrintMargin.html) class; the Spread Designer divides the inputted value by 100 in order to use the PrintMargin object which uses units of 100-ths of an inch.
