The behavior templatePrinter has all the properties to define the content area, the master page, the header, and the footer. These properties reflect the values you enter in the Page Setup dialog box and the Print Dialog box. All dimensions are stored in templatePrinter as inches. The style object, on the other hand, expects dimensions to be in 1/100th of an inch. Therefore, you need to divide the templatePrinter's settings by 100 before storing them in the style object. You also need to append the "in" dimension to every numeric value. Let's see a few examples. In these examples, assume there is a templatePrinter element with ID="printer", the master page's style object is oMasterStyleClass, and the content's style object is oContentStyleClass.

Let's start with the master page's width and height:

oMasterStyleClass.style.width = printer.pageWidth/100 + "in";
oMasterStyleClass.style.height = printer.pageHeight/100 + "in";
The margins of the content with respect to its container master page are set next:

oContentStyleClass.style.marginTop = printer.marginTop/100 + "in"; 
oContentStyleClass.style.marginLeft = printer.marginLeft/100 + "in";
