The style applied to all column headers when the grid is printed is specified by the TableView.PrintColumnHeaderStyle property. Individual columns provide the PrintColumnHeaderStyle property that, if specified, overrides the style specified by the View. This allows you to provide a custom appearance of their headers. The actual style applied to the header's contents when the grid is printed, is returned by the ActualPrintColumnHeaderStyle property.
