java遠程打印機_使用Java打印到網絡打印機

我需要發送pdf文檔以在Web應用程序的服務器端進行打印,打印機完全支持pdf打印等,它也可以聯網到服務器. pdf也存儲在服務器上.

我想要的是單擊按鈕,打印出pdf文件,目前我的代碼如下：

//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) {

}

}

}

但是我有幾個問題/問題,如何將pdf放入要打印的輸入流中,我可以選擇諸如雙面打印之類的選項,又如何從JSF Web應用程序內部調用它

謝謝
