Ehlib DBGridEh中怎样进行横向打印 / 打印预览？

答 : TPrintDBGridEh 并没有专门的属性来设置页面特性。在调用打印或打印预览方法前，你必须设置你将要执行打印的打印源（ Orientation ）。
uses ......, PrViewEh, Printers.
..............
procedure TForm1.bPreviewClick(Sender: TObject);
begin
PrinterPreview.Orientation := poLandscape;
PrintDBGridEh1.Preview;
end ;

PrintDbGrideh 打印数据

PrintDbGrideh1.BeforeGridText.Clear;//添加
PrintDbGrideh1.BeforeGridText.Add( '订单 ');
PrintDBGridEh1.PageFooter.CenterText.Text:='第 &[Page] 页/共 &[Pages] 页';
PrinterPreview.Orientation:= poLandscape;           //横向打印：需要引用 Printers 单元
PrintDBGridEh1.Options :=[pghFitGridToPageWidth];  //将所有列缩放为一页
PrintDBGridEh1.Preview;
