Java Programming

Hi,

I have an application that creates documentation in PDF format, but I need it in Postscript format (to do post processing on the documents) and send it to our printers with sockets (our printer only accepts PS documents through sockets), (I know I can use Ghostscript, but I prefer not using execute commands from within java), to fix this, I downloaded a Postscript driver from ADOBE and installed it, when I open the PDF and use File -> Print, and select Print to File option, it outputs the document in true PS format.

I then tried to do this programatically as my application will be generating 10 000 documents a day, and they need to be converted to PostScript, I used the javax.print.attribute.standard.Destination attribute when printing, but this seems to only create a copy of the file with a new extension and does not actually let the printer driver spool the document, so I am ending up with PDF documents with a PS extension. Am I doing something wrong, or is there a differant way of doing this?

I am included my source below (Please note that it is only a test app I wrote, so it is not nicely structured, as this is only for testing purposes):

import java.io.File;
import java.io.FileInputStream;

import javax.print.Doc;
import javax.print.DocFlavor;
import javax.print.DocPrintJob;
import javax.print.PrintService;
import javax.print.PrintServiceLookup;
import javax.print.SimpleDoc;
import javax.print.attribute.HashPrintRequestAttributeSet;
import javax.print.attribute.HashPrintServiceAttributeSet;
import javax.print.attribute.PrintRequestAttributeSet;
import javax.print.attribute.PrintServiceAttributeSet;
import javax.print.attribute.standard.Destination;
import javax.print.attribute.standard.PrinterName;

public class Main {

	/**
	 * @param args
	 */
	public static void main(String[] args) {
		final String PRINTER_NAME = "Generic PostScript Printer";
		final String IN_FILE = "C:/temp/InputDocument.pdf";
		final String OUT_FILE = "C:/temp/OutputDocument.ps";

		try{
			PrintServiceAttributeSet list = new HashPrintServiceAttributeSet();
			list.add(new PrinterName(PRINTER_NAME,null));
			File outFile = new File(OUT_FILE);
			if (outFile.exists()){
				outFile.delete();
			}
			DocFlavor flavor = DocFlavor.INPUT_STREAM.POSTSCRIPT;
			PrintService[] ps = PrintServiceLookup.lookupPrintServices(flavor, list);
			if (ps.length > 0){
				PrintService psServices = ps[0];
				FileInputStream file = new FileInputStream(IN_FILE);
				DocPrintJob job = psServices.createPrintJob();
				Doc doc = new SimpleDoc(file, flavor, null);
				PrintRequestAttributeSet printSet = new HashPrintRequestAttributeSet();
				printSet.add(new Destination(outFile.toURI()));
				job.print(doc, printSet);
			}
		}catch(Exception e){
			e.printStackTrace();
		}
	}

}

Please let me know if anything in my question is unclear.

Thank you in advance, any help would be greatly appreciated.
