插件Spire.PDF幫你高效搞定PDF打印

Spire.PDF介紹

Spire.PDF是一個專業的PDF組件，能夠獨立地創建、編寫、編輯、操作和閱讀PDF文件，支持 .NET、Java、WPF和Silverlight。Spire.PDF的PDF API擁有豐富的功能，如安全設置（包括數字簽名）、PDF文本/附件/圖片提取、PDF文件合並/拆分、元數據更新、章節和段落優化、圖形/圖像描繪和插入、表格創建和處理、數據導入等等。

本文將介紹以下幾種常見方式：

• 使用默認打印機打印PDF文檔

• 使用虛擬打印機（Microsoft XPS Document Writer）打印PDF文檔

• 指定打印機及PDF文檔打印頁碼范圍

• 靜默打印PDF文檔

• 雙面打印PDF文檔

• 完整打印過程

使用默認打印機

//加載PDF文檔
PdfDocument doc = new PdfDocument();
doc.LoadFromFile("Test.pdf");
//使用默認打印機打印文檔所有頁面
doc.PrintDocument.Print();

使用虛擬打印機（Microsoft XPS Document Writer）

//加載PDF文檔
PdfDocument doc = new PdfDocument();
doc.LoadFromFile("Test.pdf");

//選擇Microsoft XPS Document Writer打印機
doc.PrintDocument.PrinterSettings.PrinterName = "Microsoft XPS Document Writer";

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

指定打印機及文檔打印頁碼范圍

//加載PDF文檔
PdfDocument doc = new PdfDocument();
doc.LoadFromFile("Test.pdf");

//設置打印對話框屬性
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)
{
    //指定打印機及打印頁碼范圍
    doc.PrintFromPage = dialogPrint.PrinterSettings.FromPage;
    doc.PrintToPage = dialogPrint.PrinterSettings.ToPage;
    doc.PrinterName = dialogPrint.PrinterSettings.PrinterName;
    
    //打印文檔
    PrintDocument printDoc = doc.PrintDocument;
    dialogPrint.Document = printDoc;
    printDoc.Print();
}

靜默打印

//加載PDF文檔
var doc = new PdfDocument();
doc.LoadFromFile("Test.pdf");

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

雙面打印

//加載PDF文檔
PdfDocument doc = new PdfDocument();
doc.LoadFromFile("Test.pdf");

//判斷打印機是否支持雙面打印
bool isDuplex = doc.PrintDocument.PrinterSettings.CanDuplex;
if (isDuplex)
{
    //如果支持則設置雙面打印模式，可選：Default/Simplex/Horizontal/Vertical
    doc.PrintDocument.PrinterSettings.Duplex = Duplex.Default;
    //打印文檔
    doc.PrintDocument.Print();
}

支持選擇打印機、紙張設置、雙面打印、彩色打印、打印份數和打印頁碼范圍等等都可以進行控制！
