C# winfom 水晶报表(For VS.NET2010)设置纵向打印,打印出的却是横向的,请朋友们指点下.找出问题原因.

以编程方式实现,勿提供手动设置的方案.

代码如下:
private void 打印DToolStripMenuItem_Click(object sender, EventArgs e)
{
ReportDocument crReportDocument = new ReportDocument();
//Create an instance of a report
crReportDocument = new JcApp.Report.RptStock();// RptStock.rpt为水晶报表文件
//Use error handling in case an error occurs
try
{
//Set the printer name to print the report to. By default the sample
//report does not have a defult printer specified. This will tell the
//engine to use the specified printer to print the report. Print out
//a test page (from Printer properties) to get the correct value.
System.Drawing.Printing.PrintDocument printDocument = new System.Drawing.Printing.PrintDocument();
string strPrintName = printDocument.PrinterSettings.PrinterName;
crReportDocument.PrintOptions.PrinterName = strPrintName;

//根据指定纸张格式名称设置纸张格式
Microsoft.Win32.RegistryKey rk;
if (!strPrintName.StartsWith(@"\\")) //本地打印机
rk = Microsoft.Win32.Registry.LocalMachine.OpenSubKey("SOFTWARE\\Microsoft\\Windows NT\\CurrentVersion\\Print\\Printers\\" + strPrintName + "\\DsDriver");
else //网络打印机
{

string[] p = strPrintName.Remove(0, 2).Split(new char[] { '\\' });
string path = "SOFTWARE\\Microsoft\\Windows NT\\CurrentVersion\\Print\\Providers\\LanMan Print Services\\Servers\\" + p[0] + "\\Printers\\" + p[1] + "\\DsDriver";
rk = Microsoft.Win32.Registry.LocalMachine.OpenSubKey(path);
}
string[] papers = (string[])(rk.GetValue("printMediaSupported"));
//纸张格式名称与纸张格式id的键值对
System.Collections.Hashtable ht = new System.Collections.Hashtable();
for (int i = 0; i < papers.Length; i++)
{
ht.Add(papers[i], i);
}
//根据纸型名称在其名称列表中的索引，获取该索引在调用Get_PaperSizes后的size数组中的对应值
string strPageSizeName = "241二等分";//自定义纸张 宽度:2100mm 高度:1390mm
int[] sizes = PaperSizeGetter.Get_PaperSizes(strPrintName);
int paperSizeid = sizes[Convert.ToInt32(ht[strPageSizeName])];//sizes[this.listBoxPapers.SelectedIndex];

//将该size赋值给报表对象
crReportDocument.PrintOptions.PaperSize = (CrystalDecisions.Shared.PaperSize)(paperSizeid);

crReportDocument.PrintToPrinter(1, true, 1, 1);

MessageBox.Show("打印完成!");
}
catch (Exception err)
{
MessageBox.Show(err.ToString());
}
}

}
