The following shows how to create a custom PrintTableView resource, which will cause all data cells to be displayed DeepPink:
<xcdg:PrintTableView x:Key="customPrintView">
<xcdg:PrintTableView.PageStyle>
<Style>
<Style.Resources>
<Style TargetType="{x:Type xcdg:DataCell}">
<Setter Property="Background" Value="DeepPink" />
</Style>
</Style.Resources>
</Style>
</xcdg:PrintTableView.PageStyle>
</xcdg:PrintTableView>
Then, when you declare your DataGridControl:
<xcdg:DataGridControl PrintView="{Binding Source={StaticResource customPrintView}}" />
