java 打印

给一段代码，以前用在SWING开发中写的 import java.io.FileInputStream; import java.io.FileNotFoundException; import javax.print.Doc; import javax.print.DocFlavor; import javax.print.DocPrintJob; import javax.print.PrintException; import javax.print.PrintService; import javax.print.PrintServiceLookup; import javax.print.SimpleDoc; import javax.print.attribute.DocAttributeSet; import javax.print.attribute.HashDocAttributeSet; import javax.print.attribute.HashPrintRequestAttributeSet; import javax.print.attribute.PrintRequestAttributeSet; import javax.print.attribute.standard.MediaSizeName; import javax.swing.JOptionPane; public class PrintUtils { public static void main(String[] args) { FileInputStream textStream = null ; try { textStream = new FileInputStream( " C:\\CityLove.pdf " ); } catch (FileNotFoundException e) { // TODO Auto-generated catch block e.printStackTrace(); } // String printStr = "打印测试内容"; // 获取需要打印的目标文本 if (textStream != null ) // 当打印内容不为空时 { // 指定打印输出格式 DocFlavor flavor = DocFlavor.INPUT_STREAM.PDF; // SERVICE_FORMATTED.PRINTABLE // 定位默认的打印服务 PrintService printService = PrintServiceLookup.lookupDefaultPrintService(); // 创建打印作业 DocPrintJob job = printService.createPrintJob(); // 设置打印属性 PrintRequestAttributeSet pras = new HashPrintRequestAttributeSet(); // 设置纸张大小,也可以新建MediaSize类来自定义大小 pras.add(MediaSizeName.ISO_A4); DocAttributeSet das = new HashDocAttributeSet(); // 指定打印内容 Doc doc = new SimpleDoc(textStream, flavor, das); // 不显示打印对话框，直接进行打印工作 try { job.print(doc, pras); // 进行每一页的具体打印操作 } catch (PrintException pe) { pe.printStackTrace(); } } else { // 如果打印内容为空时，提示用户打印将取消 JOptionPane.showConfirmDialog( null , " Sorry, Printer Job is Empty, Print Cancelled! " , " Empty " , JOptionPane.DEFAULT_OPTION, JOptionPane.WARNING_MESSAGE); } } }
