Java 打印PDF文档
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:
① 静默打印
② 显示打印对话框打印
③ 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。
<repositories>
<repository>
<id>com.e-iceblue</id>
<url>http://repo.e-iceblue.cn/repository/maven-public/</url>
</repository>
</repositories>
<dependencies>
<dependency>
<groupId>e-iceblue</groupId>
<artifactId>spire.pdf.free</artifactId>
<version>2.6.3</version>
</dependency>
</dependencies>
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。
代码示例
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.*;
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());
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();
}
}
}
}
打印时自定义纸张大小
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();
//设置打印纸张大小
Paper loPaper = loPageFormat.getPaper();
loPaper.setSize(500,600);
loPageFormat.setPaper(loPaper);
loPrinterJob.setPrintable(pdf,loPageFormat);
try { loPrinterJob.print();
}
catch (PrinterException e) { e.printStackTrace();
}
}
}
