Even page header value. Corresponds to even printed pages. Even page(s) in the sheet may not be printed, for example, if the print area is specified to be a range such that it falls outside an even page's scope. If no even header is specified, then odd header value is assumed for even page headers.

The even header is activated by the "Different Even/Odd" Header/Footer property for the sheet. If this property is not set, the even header is ignored, and the odd footer is used instead.

Creating an even header or footer sets this property by default, so all you need to do to get an even header or footer to display is to create it. Likewise, if both the even header and footer are usnset, then this property is unset, and the odd header and footer are used for even pages.
