嗨

导入 System.Data .OleDb
导入 System.Data . DataTable

法蒂玛246，
Hi Fatimah246,
感谢您在MSDN论坛中发帖.
Thank you for posting in MSDN forum.
根据您的描述，我建议您可以使用 PageSetupDialog 更改打印设置.当您调用PageSetupDialog.ShowDialog()时，将出现一个对话框.
According to your description, I suggest that you could use PageSetupDialog to change the print settings. A dialog box will appear when you call PageSetupDialog.ShowDialog().
您还可以通过设置PrintDocument的DefaultPageSettings属性来设置横向格式.
You could also set the landscape format by set the PrintDocument's DefaultPageSettings property.
有关更多信息，您可以参考MSDN库: https://msdn.microsoft.com/zh-CN/library/ms404294(v=vs.100).aspx
For more information you could refer MSDN library: https://msdn.microsoft.com/en-us/library/ms404294(v=vs.100).aspx
And I found this thread about Printing preview and print in vb.net applications.
希望有帮助.
最好的问候，
