[JAVA2D] Problem in printing on specfic printer on network
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

Re: [JAVA2D] Problem in printing on specfic printer on network
Hi Shashwat,
I cannot find string "printString" anywhere in the code so I don't know which string you are
referring to that is not printed. Looking at your code though, I noticed that in order to monitor
your print job, PrintJobWatcher should implement PrintJobListener and attached to "job" which was
created using createPrintJob. See the documnetation on PrintJobListener for more information.

[JAVA2D] bad return value from GraphicsDevice.getAvailableAcceleratedMemory()?
Windows XP, SP3 java -version 1.6.0_11-b03 nvidia 8400GS with 512mb of Vram In earlier builds calling GraphicsDevice.getAvailableAcceleratedMemory() seemed to return a proper vram value. I've noticed that in more recent versions it is returning inaccurate values. On this particular machine calling it returns a value of 610 MB (639631360 bytes). On a newer vista 64 machine with an 512MB nvidia graphics card the call returns a large negative value. (about -1500MB). On a third winXP machine with a 128MB nvidia 5900 card it returns 176MB. The values are similar if I call the method right after creating the GraphicsDevice, after creating a buffer strategy, or after creating a seperate volatile image. Is this a known bug, or did something change?

Re: [JAVA2D] Problem in printing on specfic printer on network
Hi Jennifer Sorry I wrongly wrote it is not printString it is printContent, so now I edited it. I am trying your suggestion but I think so the problem that my doc favor is not recognized by printer. When I debugged my program execution goes to the printDataTransferCompleted() and then printJobNoMoreEvents() methods of PrintJobListener interface but string is not getting printed. I have HP laserjet as my network printer.

Re: [JAVA2D] bad return value from GraphicsDevice.getAvailableAcceleratedMemory()?
Unfortunately, this is just the way Direct3D 9 reports the amount of available video memory. It makes even less sense on windows Vista because video memory is virtualized there and is basically limited by your swap size. Earlier releases used DirectX 7 where the amount of vram reported was closer to the real thing.
