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文件获取及导入:
方法1:下载jar包。下载后,解压文件,并将lib文件夹下的Spire.Pdf.jar导入java程序。
方法2:可通过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,可从参考:https://www.programcreek.com/java-api-examples/java.awt.print.PrinterJob
