Printing a document to a specific printer - Linux RedHat

Question

Is it possible to print a document to a particular printer with the jdk1.4 in Linux RedHat? I am trying to select a printer with the following program (where args[0] is the name of the printer) but even though it seems that the program selects the right printer service the output allways goes to the default printer of the server.
public class PrintFile {
public static void main(String args[]) {
          String printername = args[0];
          String filename = args[1];
          if (printername != null) {
          if (filename != null) {
          try {
          javax.print.PrintService myprintservice = null;
          //Document flavor
          javax.print.DocFlavor flavor = javax.print.DocFlavor.INPUT_STREAM.POSTSCRIPT;
          //Print service for
          javax.print.attribute.PrintRequestAttributeSet aset = new javax.print.attribute.HashPrintRequestAttributeSet();
          aset.add(javax.print.attribute.standard.MediaSizeName.NA_LETTER);
          //Creating the Print Service
          javax.print.PrintService[] service = javax.print.PrintServiceLookup.lookupPrintServices(flavor,aset);
          if (service.length > 0) {
for(int i=0;i<service.length;i++) {
if (service.getName().equals(printername)) {
myprintservice = service[i];
break;
          if (myprintservice != null) {
          java.io.FileInputStream file = new java.io.FileInputStream(filename);
          javax.print.Doc doc = new javax.print.SimpleDoc(file ,flavor ,null);
          //Send the document to the printer
          javax.print.DocPrintJob pj = myprintservice.createPrintJob();
System.out.println("Printing to: " + pj.getPrintService().getName());
          pj.print(doc, null);
          file.close();
System.exit(0);
} catch(Exception e) {System.out.println(e.toString());}
Is this a bug or am I missing something?

Answer 1

Yes, I've got the same problem, too. First I get all the print services using PrintServiceLookup.lookupPrintServices(DocFlavor flavor, AttributeSet attributes)
Once I have the array of PrintService object I get the one that I'm looking for:
for (int i=0; i<services.length; i++) {
PrintService ps = services;
if (ps.getName().equalsIgnoreCase(myPrinterName)) {
myService = ps[i];
break;
But when I try to print through the object "myService" the printing always goes to the same printer!!!
