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。

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
