Selecting MediaTray in Java printing
- by Rocket Surgeon
I am trying to programmatically select a different media tray using Java Printing API. However, my document always gets printed to the default (TOP) media tray. I checked if the MediaTray attributes are supported using "isAttributeValueSupported()" method on javax.print.PrintService interface and I am getting the result as "true" for each MediaTray I pass. Here is my code:
public void print(
String printerName,
com.company.services.document.transferobject.MediaTray tray,
byte[] document) {
String methodName = "print: ";
logger.sendEvent(CLASS_NAME + methodName + "Start", EventType.INFO,
this);
if (printerName == null || "none".equals(printerName)
|| "?".equals(printerName) || "null".equals(printerName)) {
logger.sendEvent("Please supply printer name, currently printerName is "+printerName,
EventType.INFO, this);
return;
}
DocFlavor flavor = DocFlavor.BYTE_ARRAY.AUTOSENSE;
AttributeSet attributeSet = new HashAttributeSet();
attributeSet.add(new PrinterName(printerName, null));
javax.print.PrintService service = getService(printerName);
if (service.isAttributeValueSupported(MediaTray.TOP, flavor, null)) {
System.out.println("---------->>>>>>>>>Yes TOP" + " : Value : "
+ MediaTray.TOP.getValue());
} else {
System.out.println("---------->>>>>>>>>Nope");
}
if (service.isAttributeValueSupported(MediaTray.BOTTOM, flavor, null)) {
System.out.println("---------->>>>>>>>>Yes BOTTOM" + " : Value : "
+ MediaTray.BOTTOM.getValue());
} else {
System.out.println("---------->>>>>>>>>Nope");
}
if (service.isAttributeValueSupported(MediaTray.MIDDLE, flavor, null)) {
System.out.println("---------->>>>>>>>>Yes MIDDLE" + " : Value : "
+ MediaTray.MIDDLE.getValue());
} else {
System.out.println("---------->>>>>>>>>Nope");
}
if (service.isAttributeValueSupported(MediaTray.MANUAL, flavor, null)) {
System.out.println("---------->>>>>>>>>Yes MANUAL" + " : Value : "
+ MediaTray.MANUAL.getValue());
} else {
System.out.println("---------->>>>>>>>>Nope");
}
if (service.isAttributeValueSupported(MediaTray.SIDE, flavor, null)) {
System.out.println("---------->>>>>>>>>Yes SIDE" + " : Value : "
+ MediaTray.SIDE.getValue());
} else {
System.out.println("---------->>>>>>>>>Nope");
}
DocPrintJob printJob = service.createPrintJob();
try {
byte[] textStream = document;
PrintRequestAttributeSet pras =
new HashPrintRequestAttributeSet();
pras.add(DocumentServiceConstant.
DEFAULT_ONE_PRINT_COPY);
pras.add(Sides.ONE_SIDED);
Media standardTray= toStandardTray(tray);
if (null != standardTray) {
pras.add(standardTray);
}
Doc myDoc = new SimpleDoc(textStream, flavor, null);
printJob.print(myDoc, pras);
logger.sendEvent(
" successfully printed ............ ",
EventType.INFO, this);
} catch (Throwable th) {
logger.sendEvent(" Throwable : "+th.getLocalizedMessage(),
EventType.INFO, this);
ExceptionUtility
.determineExceptionForServiceClient(th);
}
logger.sendEvent(CLASS_NAME + methodName + "END: ", EventType.INFO,
this);
}
Any help will be greatly appreciated!
