以下内容归纳了通过Java程序打印PDF文档时的3种情形。即:

  •    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:Spire.PDF for Java

Jar导入

方法1通过官网下载jar包。

方法2通过maven库导入。参考导入方法

 

Java代码示例

【示例1】静默打印

即通过使用默认打印机直接打印PDF文档。打印时,我们可以设置打印份数,设置纸张打印页边距等。

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("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();
        }
    }
}

【示例2】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("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();
            }
        }
    }
}

【示例3】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("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();
        } 
    }
}
如果需要更详细的打印设置,可以在PrinterJob下设置相应的参数,可参考:https://www.programcreek.com/java-api-examples/java.awt.print.PrinterJob
