Spire.Pdf 组件支持多种 PDF 文档打印方式。本文适用于 Spire.PDF Hotfix Version 3.9.360 之前的版本或免费版本，如果你使用的是该版本之后的新版本，请参考这篇文章。

本文将介绍以下几种常见方式：

• 使用默认打印机打印PDF文档
• 使用虚拟打印机（Microsoft XPS Document Writer）打印PDF文档
• 指定打印机及PDF文档打印页码范围
• 静默打印PDF文档
• 双面打印PDF文档

使用默认打印机

//加载PDF文档
PdfDocument doc = new PdfDocument();
doc.LoadFromFile("Test.pdf");
//使用默认打印机打印文档所有页面
doc.PrintDocument.Print(); 

'加载PDF文档
Dim doc As New PdfDocument()
doc.LoadFromFile("Test.pdf")
'使用默认打印机打印文档所有页面
doc.PrintDocument.Print()

使用虚拟打印机

虚拟打印机（Microsoft XPS Document Writer）

//加载PDF文档
PdfDocument doc = new PdfDocument();
doc.LoadFromFile("Test.pdf");

//选择Microsoft XPS Document Writer打印机
doc.PrintDocument.PrinterSettings.PrinterName = "Microsoft XPS Document Writer";

//打印PDF文档到XPS格式
doc.PrintDocument.PrinterSettings.PrintToFile = true;
doc.PrintDocument.PrinterSettings.PrintFileName = "PrintToXps.xps";
doc.PrintDocument.Print();

'加载PDF文档
Dim doc As New PdfDocument()
doc.LoadFromFile("Test.pdf")

'选择Microsoft XPS Document Writer打印机
doc.PrintDocument.PrinterSettings.PrinterName = "Microsoft XPS Document Writer"

'打印PDF文档到XPS格式
doc.PrintDocument.PrinterSettings.PrintToFile = True
doc.PrintDocument.PrinterSettings.PrintFileName = "PrintToXps.xps"
doc.PrintDocument.Print()

指定打印机及文档打印页码范围

//加载PDF文档
PdfDocument doc = new PdfDocument();
doc.LoadFromFile("Test.pdf");

//设置打印对话框属性
PrintDialog dialogPrint = new PrintDialog();
dialogPrint.AllowPrintToFile = true;
dialogPrint.AllowSomePages = true;
dialogPrint.PrinterSettings.MinimumPage = 1;
dialogPrint.PrinterSettings.MaximumPage = doc.Pages.Count;
dialogPrint.PrinterSettings.FromPage = 1;
dialogPrint.PrinterSettings.ToPage = doc.Pages.Count;

if (dialogPrint.ShowDialog() == DialogResult.OK)
{
    //指定打印机及打印页码范围
    doc.PrintFromPage = dialogPrint.PrinterSettings.FromPage;
    doc.PrintToPage = dialogPrint.PrinterSettings.ToPage;
    doc.PrinterName = dialogPrint.PrinterSettings.PrinterName;
    
    //打印文档
    PrintDocument printDoc = doc.PrintDocument;
    dialogPrint.Document = printDoc;
    printDoc.Print();
}

'加载PDF文档
Dim doc As New PdfDocument()
doc.LoadFromFile("Test.pdf")

'设置打印对话框属性
Dim dialogPrint As New PrintDialog()
dialogPrint.AllowPrintToFile = True
dialogPrint.AllowSomePages = True
dialogPrint.PrinterSettings.MinimumPage = 1
dialogPrint.PrinterSettings.MaximumPage = doc.Pages.Count
dialogPrint.PrinterSettings.FromPage = 1
dialogPrint.PrinterSettings.ToPage = doc.Pages.Count

If dialogPrint.ShowDialog() = DialogResult.OK Then
	'指定打印机及打印页码范围
	doc.PrintFromPage = dialogPrint.PrinterSettings.FromPage
	doc.PrintToPage = dialogPrint.PrinterSettings.ToPage
	doc.PrinterName = dialogPrint.PrinterSettings.PrinterName

	'打印文档
	Dim printDoc As PrintDocument = doc.PrintDocument
	dialogPrint.Document = printDoc
	printDoc.Print()
End If

静默打印

//加载PDF文档
var doc = new PdfDocument();
doc.LoadFromFile("Test.pdf");

//静默打印PDF文档
PrintDocument printDoc = doc.PrintDocument;
printDoc.PrintController = new StandardPrintController(); 
printDoc.Print();

'加载PDF文档
Dim doc = New PdfDocument()
doc.LoadFromFile("Test.pdf")

'静默打印PDF文档
Dim printDoc As PrintDocument = doc.PrintDocument
printDoc.PrintController = New StandardPrintController()
printDoc.Print()

双面打印

//加载PDF文档
PdfDocument doc = new PdfDocument();
doc.LoadFromFile("Test.pdf");

//判断打印机是否支持双面打印
bool isDuplex = doc.PrintDocument.PrinterSettings.CanDuplex;
if (isDuplex)
{
    //如果支持则设置双面打印模式，可选：Default/Simplex/Horizontal/Vertical
    doc.PrintDocument.PrinterSettings.Duplex = Duplex.Default;
    //打印文档
    doc.PrintDocument.Print();
}

'加载PDF文档
Dim doc As New PdfDocument()
doc.LoadFromFile("Test.pdf")

'判断打印机是否支持双面打印
Dim isDuplex As Boolean = doc.PrintDocument.PrinterSettings.CanDuplex
If isDuplex Then
	'如果支持则设置双面打印模式，可选：Default/Simplex/Horizontal/Vertical
	doc.PrintDocument.PrinterSettings.Duplex = Duplex.[Default]
	'打印文档
	doc.PrintDocument.Print()
End If
