java远程打印机_使用Java打印到网络打印机

我需要发送pdf文档以在Web应用程序的服务器端进行打印,打印机完全支持pdf打印等,它也可以联网到服务器. pdf也存储在服务器上.

我想要的是单击按钮,打印出pdf文件,目前我的代码如下：

//Server side printing

public class PrintDocument {

public void printText(String text) throws PrintException, IOException {

//Looks for all printers

//PrintService[] printServices = PrintServices();

PrintService rvice = DefaultPrintService();

InputStream is = new ByteArrayInputStream(es("UTF8"));

PrintRequestAttributeSet pras = new HashPrintRequestAttributeSet();

(new Copies(1));

DocFlavor flavor = _NSE;

Doc doc = new SimpleDoc(is, flavor, null);

DocPrintJob job = PrintJob();

PrintJobWatcher pjw = new PrintJobWatcher(job);

(doc, pras);

rDone();

();

}

}

class PrintJobWatcher {

boolean done = fal;

PrintJobWatcher(DocPrintJob job) {

ntJobListener(new PrintJobAdapter() {

public void printJobCanceled(PrintJobEvent pje) {

allDone();

}

public void printJobCompleted(PrintJobEvent pje) {

allDone();

}

public void printJobFailed(PrintJobEvent pje) {

allDone();

}public void printJobNoMoreEvents(PrintJobEvent pje) {

allDone();

}

void allDone() {

synchronized () {

done = true;

n("Printing has successfully completed, plea collect your prints)");

();

}

}

});

}

public synchronized void waitForDone() {

try {

while (!done) {

wait();

}

} catch (InterruptedException e) {

}

}

}

但是我有几个问题/问题,如何将pdf放入要打印的输入流中,我可以选择诸如双面打印之类的选项,又如何从JSF Web应用程序内部调用它

谢谢
