本文将介绍如何在Java应用程序中打印PDF文档。一般有以下三种常见打印方式：静默打印

显示打印对话框打印

打印PDF时自定义纸张大小

使用工具：Free Spire.PDF for Java

创建运行环境：

方式 1：通过官网下载组件，解压后将lib文件夹下的Spire.Pdf.jar手动导入IDEA中。具体步骤可参考下图。

方式 2：通过Maven仓库安装产品及导入相关依赖包。在pom.xml文件中配置Maven仓库路径，及指定Free Spire.PDF for Java的Maven依赖。

com.e-iceblue

http://repo.e-iceblue.cn/repository/maven-public/

e-iceblue

spire.pdf.free

2.6.3

配置完成后，在IDEA中，您只需点击"Import Changes"即可导入JAR包；在Eclipse中，则需点击"Save"按钮。

代码演示

静默打印import com.spire.pdf.*;

import java.awt.print.*;

public class Print {

public static void main(String[] args) {

//加载文档

PdfDocument pdf = new PdfDocument();

pdf.loadFromFile("C:\\Users\\Test1\\Desktop\\Sample.pdf");

PrinterJob loPrinterJob = PrinterJob.getPrinterJob();

PageFormat loPageFormat = loPrinterJob.defaultPage();

Paper loPaper = loPageFormat.getPaper();

//删除默认页边距

loPaper.setImageableArea(0,0,loPageFormat.getWidth(),loPageFormat.getHeight());

//设置打印份数

loPrinterJob.setCopies(2);

loPageFormat.setPaper(loPaper);

loPrinterJob.setPrintable(pdf,loPageFormat);

try {

loPrinterJob.print();

} catch (PrinterException e) {

e.printStackTrace();

}

}

}

显示打印对话框打印PDF文档import com.spire.pdf.*;

loPageFormat.setPaper(loPaper);

loPrinterJob.setPrintable(pdf,loPageFormat);

//显示打印对话框

if (loPrinterJob.printDialog()) {

try {

loPrinterJob.print();

} catch (PrinterException e) {

e.printStackTrace();

}

}

}

}
