Hi Everyone
I am working one swing application which need to print on some specific
printer on network. Method which I am using is given below. In this
method i am passing the printer name as parameter and string which is
to be printed is present in the class member [b]printString[/b].
public boolean print(String printerName) {
boolean result = false;
try {
ByteArrayInputStream bais = new
ByteArrayInputStream(printContent.getBytes());
PrintService[] services =
PrinterJob.lookupPrintServices();
String [] printerNameList = new String[services.length];
for(int count = 0; count < services.length; count++) {
printerNameList[count] =
services[count].getName();
if
(printerNameList[count].equalsIgnoreCase(printerName)) {
DocPrintJob job =
services[count].createPrintJob();
DocFlavor flavor =
DocFlavor.BYTE_ARRAY.AUTOSENSE;
Doc doc = new
SimpleDoc(printContent.getBytes(), flavor, null);
PrintRequestAttributeSet attributes =
new HashPrintRequestAttributeSet();
attributes.add(new Copies(1));
PrintJobWatcher pjDone = new
PrintJobWatcher(job);
job.print(doc, attributes);
pjDone.waitForDone();
bais.close();
result = true;
break;
}
}
}
catch(PrintException ex) {
String message = "Error on while printing the content
on the printer : " + ex.getMessage();
System.out.println(message);
ApplicationLogger.getInstance().error(message);
}
catch(Exception ex) {
String message = "Error on while printing the content :
" + ex.getMessage();
System.out.println(message);
ApplicationLogger.getInstance().error(message);
}
return result;
}
Here is the code for PrintJobWatcher
class PrintJobWatcher {
// true iff it is safe to close the print job's input stream
boolean done = false;
PrintJobWatcher(DocPrintJob job) {
// Add a listener to the print job
job.addPrintJobListener(new PrintJobAdapter() {
public void printJobCanceled(PrintJobEvent event) {
allDone();
}
public void printJobCompleted(PrintJobEvent event) {
allDone();
}
public void printJobFailed(PrintJobEvent event) {
allDone();
}
public void printJobNoMoreEvents(PrintJobEvent event) {
allDone();
}
void allDone() {
synchronized (PrintJobWatcher.this) {
done = true;
PrintJobWatcher.this.notify();
}
}
});
}
public synchronized void waitForDone() {
try {
while (!done) {
wait();
}
}
catch (InterruptedException e) {
}
}
}
But my string is not being printed. Please tell where I am doing mistake.
Thanks in advance
