服务器端：

package test.print;    import java.io.File;  import java.io.FileInputStream;  import java.io.FileNotFoundException;    import javax.print.Doc;  import javax.print.DocFlavor;  import javax.print.PrintException;  import javax.print.PrintService;  import javax.print.PrintServiceLookup;  import javax.print.ServiceUI;  import javax.print.SimpleDoc;  import javax.print.attribute.HashPrintRequestAttributeSet;  import javax.print.attribute.PrintRequestAttributeSet;    public class Print {  public static void main(String[] args) throws PrintException,  FileNotFoundException {  // get all printers  PrintService[] printers = PrintServiceLookup.lookupPrintServices(null,  null);  // get default printer  PrintService defaultPrinter = PrintServiceLookup  .lookupDefaultPrintService();  // the contentType which to be printed  DocFlavor flavor = DocFlavor.INPUT_STREAM.JPEG;  // print attrituters  PrintRequestAttributeSet attrs = new HashPrintRequestAttributeSet();  // get a printer  PrintService dps = ServiceUI.printDialog(null, 100, 100, printers,  defaultPrinter, null, attrs);  // new one document  Doc doc = new SimpleDoc(new FileInputStream(new File(  "C:\\Users\\Administrator\\Pictures\\我的图片\\computer.jpg")),  flavor, null);  // print  dps.createPrintJob().print(doc, attrs);  }  }

客户端：

import java.applet.Applet; import java.net.MalformedURLException; import java.net.URL;  import javax.print.Doc; import javax.print.DocFlavor; import javax.print.PrintException; import javax.print.PrintService; import javax.print.PrintServiceLookup; import javax.print.ServiceUI; import javax.print.SimpleDoc; import javax.print.attribute.HashPrintRequestAttributeSet; import javax.print.attribute.PrintRequestAttributeSet;  public class Print extends Applet { private static final long serialVersionUID = 1L;  public void init() { // get all printers PrintService[] printers = PrintServiceLookup.lookupPrintServices(null, null); // get default printer PrintService defaultPrinter = PrintServiceLookup .lookupDefaultPrintService(); // the contentType which to be printed DocFlavor flavor = DocFlavor.URL.JPEG; // print attrituters PrintRequestAttributeSet attrs = new HashPrintRequestAttributeSet(); // get a printer PrintService dps = ServiceUI.printDialog(null, 100, 100, printers, defaultPrinter, null, attrs); // new one document try { Doc doc = new SimpleDoc(new URL( "http://localhost:8080/ncTest/computer.jpg"), flavor, null); // print dps.createPrintJob().print(doc, attrs); } catch (PrintException e) { e.printStackTrace(); } catch (MalformedURLException me) { me.printStackTrace(); } } }
